SRM Intake install step by step

[SlickMachine]

Finished install, plus JHM hoses. Hopefully the 3rd O-Ring that comes with the intake is extra... ?

I found this pretty straightforward. Throttle body absolutely has to come off. There is no way to get at the bottom bolts on the intakes at the turbo otherwise. I had no issues getting any of the hoses off. My engine was very warm, I had driven about an hour prior and I think that helps with the hoses being more malleable. I did the shorts to the stock S7 air box, I didn't notice any fitment problems with the driver's side inlet, however it is not possible to see the union between the turbo housing and intake pipe on the passenger side of the driver's turbo , so I'm trusting it's sealed there. The fit is extremely close, and the inlet pipes touch. I'm guessing the car would throw codes if there was a leak there but I can see how some decide that the pipe needs modded/heated/bent. I had to cut the infamous last screw to get it to drop into place in throttle body. Took 5 mins and a hack saw. Know that the screw is just that- a screw. I had it in my head that it was a fine thread bolt and that cutting it could cause an issue getting it to thread properly. This screw is very course thread and screws into the plastic of the intercooler.
The easiest part of this install was putting the JHM hoses in place. I did this with the throttle body reinstalled. I simply folded the JHM hose and pressed it down over the inlet/outlets while twisting a lil and they slid right on, like 30 seconds each. If you're thinking of tackling this I would consider the JHM option - I actually tore one of the stock hoses with my screw driver while unsticking the rubber from the metal inlet. They are rather thin, the JHM versions are quite thick. Car has 36k miles on it.
I flashed stage 2 DS1 and took it for a quick drive but haven't been able to really get on it yet. Waiting for lambdas to catch up, and need some highway. I will say that I did not notice any increase in intake sound with the shorts to stock box, which is definitely what I was going after.

Thanks for the write up. Not too different from the s8+ install. I didn't need to take TB off (I did to put the tb spacer in but reinstalled before putting the intake on). In addition to some of the posts on install tools I would recommend a t30 socket and a 5mm allen socket. Using my motorcycle tiny socket wrench thing that takes screwdriver bits came in hand since I didn't have those sockets.

JHM tubes went in with lots of struggle at first. Fold them, put in upside-down and then twist and they will go into place.

The only fitment issue I had was the first hose for the driver side tube ... as it approaches the throttle body the tube protruding towards the front of the engine (recirculation?), sits on the throttle body ... could not get hose and clamp installed ...!! I was thinking ... Dam ... need to send back to SRM ... as 'it did not fit' ...!! that first tube needs to be moved up stream by about 5 mm more ...!!

I took the throttle body back off ... loosened the 2 bolts holding the driver's side intake tube, pressed down hard, trying to rotate the first out pipe away from the throttle body, to allow enough room for the hose and clamp to be mounted on ... the hose and clamp ride against the throttle body ... I figure the engine as a whole vibrates at the same frequency ... but, am worried about friction and future problems ...??

Installed the RS7 airbox ... which is pita ... to align the 3 rubber grommets and front grill intake ... (arrgghh)

First drive ... the car felt slower ...?? Now, a couple of weeks later ... it feels very responsive ... maybe the ECU needed to relearn, due to the change ...??

Next ... Stage 1 ECU & TCU ...

If you don’t use a tune they’re worthless. Skip stage 1 and go to DS1 stage 2

If I'm tuned APR stage 3 and install these will it adapt to the increased flow or is a more specific tune like DS1 required?

They won’t do anything. It’s not a matter of ds1 specific use but the tune isn’t taking advantage of that bottleneck being freed up

Just did this. I followed the OP's guide for much of the install, but instead of pulling the throttle body hoses, I just loosened them at the turbo's and pulled the throttle body/hoses together. There is plenty of wire/hose length to get everything out of the way.

As with some, my biggest issue was the passenger side rear screw for the throttle body, I had to shorten mine to get everything back together. There was no way it would go in at the original length, even though it was installed prior to placing the throttle body in position.

Somewhere along the line, I managed to put a small dent in one of the pipes, but what's done is done. All in, it probably took about 1.5hrs, but I took my time. Reading everyone else's posts really helped.

Currently running DS-1 Stage 3 w/ RS7 Turbos, AMS Downpipes w/high flow cats, EPL TCU Tune and SRM Intake................ :D :D :D

Still chasing O2 Sensor issues, so I'll probably look into the adapters/spacers for the rear sensors. I was hoping the AMS downpipes w/cats wouldn't need them, but it appears my setup does.

I read this entire thread - maybe I missed it but..... does anyone actually have accurate numbers for power gains?
I have a stock S7 and am considering adding an intake of some kind - CTS Turbo, SRM... but I certainly dont want to waste my time if they dont actually increase power. Thanks.

If you are stock you won't really see any power gains. You need a tune to increase boost before the inlets really become a restriction.

This. Those other brand intakes they named really show 0 benefit.

I've been following this thread for months. As with others, been waiting for SRM intakes to arrive. I ordered through Eurocode along with some other stuff in early September and received in late December. Finally got the chance to install today.

Most of what everyone else says is spot on. Depending on the tools/extensions that you have, the job can be easier or more difficult. It took me maybe two hours. Yeah, those short throttle body tubes are certainly a pain, very difficult to get unstuck, but not too bad getting back on, especially if you remove the throttle body as I did. I used some plastic trim removal tools so to not scratch or tear too much, but mostly it takes just getting really aggressive with them. If taking off throttle body, which I definitely recommend, since it is so easy anyway, need that longer Torx T30. As for other tools, basic screwdrivers, socket extensions and wobble extensions. I did find that an L shaped hex key was handy for one of the 5mm bolts. I was able to get the that last passenger side rear screw in the throttle body, without cutting it short, by just scraping by on the tube a bit, but it might be because ...

My intake tubes from SRM appear to be a new version. They come as two pieces per tube now. I confirmed through SRM because they were different than all the previous pictures (they haven't updated their web site yet). My tubes don't touch each other and I also did not have to trim off anything from the top heat/engine cover as one person mentioned. Getting the couplers and clamps on though was very tight and needed some persuasion because the tubes are so close together at that point.

I applied DS1 Stage2 tune and drove around a bit. I am running without the stock air box. I have to say I was really surprised about the various new sounds. Not sure that I like it really (the sounds). I might see if I can fit the air box back in or not. We'll see. For now, will let the computer figure things out. I have winter performance tires on right now anyway, never tried draggy with them on, I guess it wouldn't hurt sometime. I probably should wait until the weather is clear and salt off the roads anyway to really test it out (northeast Ohio).

Looks like enough people complained to SRM about having to remove their intake to change spark plugs!

Now people can complain about the updated ones!

Try changing these two tables in your Stage 2 file to the RS7 values, see if it gets rid of your new lift throttle sounds while driving gently. Turbo whine and wooshes when letting off under high boost will still be there of course.

I’m curious to know if that is what SRM is still shipping? Their website still shows. Single piece, unless they’ve done away with the short and/or 2 piece entirely to go back to the original design

Also, I’m trying to figure out a fitment issue, regarding the PCV hose, and if the drivers side inlet contacts it at all, or any clearance issues with the hose anywhere else with the SRM. I saw one post here somewhat mention it. I’ve purchased and now am returning two different manufacturers inlets, specifically ECS tuning, which was well made, but the inlet tube was clocked so that the throttle body connector contacted the hose inlet, and they then said it wasn’t compatible when I asked about it. Also their couplers didn’t fit right to RS7 sized airbox, which was frustrating. Then I have one from ARM Motorsports, which is an odd design that doesn’t align well with stock airbox (they sell their own intake filter/shield, but separately), but it would squeeze the PCV hose slightly as it came up from the valve, and then would also cause the hose contact the throttle body assembly slightly. Was concerned that could potentially lead to premature failure of the PCV hose. Not end of the world, but I also want reliability and not to have to pull these pieces every 5k just to check either.

Needless to say, I’m getting good at changing out the turbo inlets :l

[qcrazy]

Not sure what SRM makes now, someone else can answer that.

But any of the large inlets will lay on the PCV hose, completely normal. Not an issue.

As far as hooking it up with the airbox, I bought SRM long inlets and cut them to length. It is a tight fit, but the stock RS7 accordion hoses will work. One of my long inlets was fab'd incorrectly, so I had to add a second coupler to get one of mine to line up...typically not needed. But it works fine, no issues...

I’ve had these installed for nearly 2 years and they’ve been great! But recently I now have an air intake leak code and a high pitched sound ..

Anyone ever encounter this?
