TT Bolt Down Coilpacks

[A4ringedONE8T]

Anyone tried them in our car? I need to try another set of CP's and thats all I have extra at the shop right now. Car has been breaking up the last few weeks randomly on high boost. Filling up with 100 tomorrow so I want to get rid of the shit break up before I waste the money on the race gas.

Thanks, Shawn

try the Hitachi 'E' coilpacks. I've blown quite a few of the oem ones (7 or 8 I think), but haven't had a problem with the E's for well over 30,000 miles.

[A4ringedONE8T]

What are those from?

Ive had the same set of R's for almost 2 years without popping one. Ive just recently started getting some break up on high boost with high load. I have yet to get a misfire code though, just trying to eliminate possible causes

[ThatGuyAlex]

Are the RS4 ones any different besides being red?

[Silence]

TT should be hitachi, so yes, you can use them.

[sean1.8t]

shawn, for your setup, why not go with those plasma ones?

if you've got all the air and fuel you need, it wont matter if you don't have good enough spark to ignite it

[b6onboost]

I've been told the Red OEM S4/RS4 coilpacks will not work on 1.8Ts. I'm guessing its due to differing lengths.

Hitachi E bolt downs work great.

what spark plugs are you running? might want to consider a heat range cooler. I am not sure what OEM application the the E packs came originally on, but I know they are from pre-2001 1.8T engines. You can pick up a set at ECS tuning for around $130 for 4.

[A4ringedONE8T]

I usually run Denso IK27's, 3 steps colder than OEM. Ive got 7E's in right now, put them in a few days ago to make sure it wasnt the plugs

[A4ringedONE8T]

And I own my own shop, I can buy any of the OEM coilpacks from the dealer or from Worldpac for less than a 100 bucks for 4, that wasnt the point. Just trying to figure out what the problem is for sure. I have a set of spare CP's from a AMU TT at the shop, I do not have any extra R's. Just trying to not buy shit for the hell of it

[mtbrider]

I have the plasma coils

throw them in . . . see how it works. If you need the part number, the E version is the same as the R . . . just replace the R with an E. 100 octane gas might help but it's just too expensive to run all the time. When you say "breaking up the last few weeks randomly on high boost" . . . can you describe it a bit more? Pinging, boost fluttering, etc. ?

sound like what i was explaining in my track thread...

You've never been in a higher HP turbo car that breaks up in boost? Dont know how to explain it to you if you havent felt it

[A4ringedONE8T]

Just went and reread your thread and yup, same shit. Feels like a misfire or blown coilpack but no codes and it cleans up as quick as it happens

[vdubstreets]

There was/is a company that makes bolt downs that hold the coil packs down to the valve cover.

[A4ringedONE8T]

There was a comapany that made bold downs that hold the coil packs down that bolt to the valve cover. saw it on vortex

lol did you even read the thread?

[vdubstreets]

my assumption was that you were having problems with coil's popping so i figured that may help you out.

and you've changed/regapped your plugs to no avail? im hoping that cleans it up to me, although i feel like it will end up being a coil pack for me as well

Why the hell post if your "assuming" what a thread is about, like I said you didnt even read the thread ...

[rxrep]

E's FTW here. Although hitachi isn't the brand anymore.They got bought out.
I'll never go back to pop-in's, regardless of the revision. Those are my spares, but so far, so good.

[A4ringedONE8T]

Nope, I checked the gap on the IK27's I had in and also got a new set of 7E's and still does the same thing

Good to know, thanks

Car has been breaking up the last few weeks randomly on high boost.

That, and the title of the post "bolt down coilpacks" lends to me thinking your misfire up top is due to popping coils or loose coils. Which gives a good explanation to why I responded to the post to the way I did with the tie-down's. I DID read your post don't need to jump down my throat for someone trying to help out.

I had a friend with a similar issue and this resolved it.

[3thrd_a_4]

I've been using those coilpacks for 6 months now with no issues. No loss of power

If they were popping up the car would definitely not run at all after it popped up and for sure throw a CEL with misfire codes, not clear up and keep running

[mtbrider]

Before I put the plasma coils in, I was running the TT ones. I had no problems with them. If it only happens sometimes at high boost, I would also check your meth system. I was having a similar problem with my car and it turned out that with my new set-up I had to tweak my meth settings a little

[vdubstreets]

ill just pm you.

[GTMRS4]

yeah I had that same issue a few weeks back - turns out that it was due to the meth killing the spark

wtf are you talking about

are you drunk?

Ive had my meth for ever and never had an issue with it. On top of that was running the car just like it is for weeks. One day on my way home when I was logging, I did a couple pulls and it was fine, then the next one it started breaking up. Has been doing it ever since on 27psi, nothing on lower boost. Its something with the spark, and my R's are almost 2 years old.

This might be a tangent topic, but isn't there any concern that the Hitachi coils (or whomever bought them out) does not seal properly to the AMB valve cover due to the ridges in the cover?

Note the ridge that exists where each coil would go (courtesy of A4Mods.com):


Now take a look at the OEM coil:


The seal will exist at the top of the shaft, but not under the edge of the base (where the wire plugs in).

For the Hitachi coil:


Because the seal exists along the outer edge of the base, I would think that air gaps would exist due to the ridges in the valve cover.

Wouldn't this affect performance if the chance exists for something to get inside?

couldn't of made it any clear, the OP understood what i was saying.




good point. ignore the stuff on the right.

[widgget]

i have red capped packs, from ECS i think... haven't ever had a problem with them.

[dougyfresh]

The AMU valve cover has a different interface than the AMB valve cover for sealing the coil pack down on the cover.

I am not sure if the hitachi coils will seal down as cyberpmg has alluded to.

Will they stay connected to the spark plug and not jump around? My guess is yes, if you bolt them down. The AMB valve cover does have provisions for bolting down coil packs.

I could go pull my AMU coil packs out of the box they are in and put them on my AMB valve cover tonight to verify but Shawn can do the same.

I haven't had problems with mine . . . I've found nothing inside yet. Wouldn't really worry about it.

OP . . . just wasn't sure what you meant by boost breaking up. It's hard to know what people on the forum are talking about when no-one but them can hear what's going on with their car. Have you read any fault codes on it? Coil packs, plugs, too large a plug gap, MAF air ratio . . . who knows . . . Good luck though.

[GTMRS4]

Well if you CPs are almost 2 yrs old they could also be heading out...I put on the hitachi "E"s which is off of the B5 i believe. Very reliable.

Already tried different plugs, dont have a MAF, and no codes

No issues here and I run that valve cover on a AEB head on my ATW block with the Hitachi/Beru coil packs.

Came stock on the 2000 ATW A4 1.8t, I still run these on my car with the stand alone.

What I meant to say is that the OP was about failed coil packs or failing CP's not actually popping out.
