Roc Euro vs CTS

[carlosvjr92]

So there's probably been threads on this before, but I can't seem to find any of them. Trying to decide which one to go with, but they're so similar that it's hard to decide if anybody's had personal experience with both or either of them and can chime in that would be great.

From what I know so far, the CTS is a perfected version of the Roc Euro and has nearly identical sound and power gains along with better customer service...so I am leaning more toward CTS right now

[waxxonMTL]

roc euro has bad customer service. so cts choice is easy.

[GRUMPY-S4]

Its a toss up between both. Seems like CTS had better Customer Service (which is saying a lot as I have had horrible experiences dealing with Clay and CTS).

[mjfloyd1]

Roc Euro is fine customer service wise if you call. Email not so much.

Based off that alone I think CTS is the move

[bhvrdr]

I agree with the above but i'll add to it.


The CTS and Roc Euro are identical in intake tube dimensions. The heat shields are also about identical in the area that they cover.


There are differences though.

1. The CTS has a better method of attaching the heat shield in place. It uses bolts that slide into the factory airbox grommets to hold it in place. The roc euro heat shield you have to wedge between the grommets and the frame. It's kind of half a$$ IMO. You wedge it in there.

2. The CTS includes a billet air breather holder that mounts the air tube to a factory airbox mounting location at the fender. Is this needed? no, but its a nice touch.

3. The air filter quality used by the CTS has come into question. There are some people who have shown the air filter literally disintegrating and being sucked into the air intake tract in little fibers/pieces. I dont know who the manufacturer of the filter is but i'd look into it. I dont know the manufacturer of the Roc Euro filter either or it if it is better but i'd probably want to know if I was buying again. You can alway source a quality filter from an aftermarket if you are worried about it.

Both should suit your needs.

Roc-Euro has been proven worry free, CTS has had at least 1 report of filter degradation issues (that I've personally seen). +1 Roc
CTS is cheaper and comes with a billet mount vs Roc's zip tie. +1 CTS
Roc is cleaner looking by not having logo on the intake and a cleaner heat shield design. +1 Roc
CTS will probably ship this week, Roc will probably ship next month (hopefully). +1 CTS

Both have rubbing issues. -1 Roc & CTS

Thanks for pointing all of that out. I do recall seeing a thread about the CTS filter. Could always replace it with a higher quality one so that's not an issue. I believe K&N should have one that fits on CTS

I'm planning on wrapping the tube and heat shield in reflect-a-gold regardless so looks aren't a major issue for me. I'm not sure if it will actually yield any real gains, but worth a shot and CTS doesn't look bad as is IMO. Won't be opening up my hood that often anyways. If I wanted looks I'd probably go with ECS or APR. Thanks

IMO, not really acceptable for a business operating in 2016. I understand if that's the way it is with them, but it's time to catch up with the times.

My thoughts exactly. Plus if they work Mon - Fri 8-5 I'll almost never be able to call them because I work those same hours. If I can't send an email and get a response within the day it's a deal breaker for me

I agree with this assessment. As one of the people who has experienced the filter degradation issue, I would say that I should have taken the difference in price (I paid $280 for CTS vs. $330 MSRP for Roc) and spent it on a high-quality, proven alternative aftermarket filter. The potential challenge would be finding on that has the same inlet hole diameter and same length so as to not interfere with the headlight wire harness.

[carlosvjr92]

Theoretically - if CTS and Roc Euro are the same dimensions couldn't I just order a roc euro replacement filter and that will fit just fine?

Good to know! I may be ordering today

[A.C.]

I have the cts turbo intake and have nothing but good praises. It was installed 3 months ago and logged over 5k and no issues including rubbing on the AC line. Although I did pick up a rubber hose to cover the line just in case.

No issues with the filter degrading yet?

This would be true if the length and angle of the tubes is the same, and if the inlet diameter of the tubes are the same. However if I were to go this route, I would spend my $40-50 on a known quality aftermarket filter (K&N, AFE etc) instead of going for the Roc-Euro which, as far as we know, is also a "mystery brand" (albeit one with no reported failures that we know of). But again, you would need to take measurements of your CTS filter and make sure that the new filter you are buying fits within those same measurements.

[SteveYem]

FWIW, CTS did send me a replacement filter for the one I had that had started to disintegrate after < 10k miles of use, and what I noticed immediately about the replacement is that it appears to be adequately oiled, whereas I do not recall noticing the same with the filter that was originally supplied with the intake. It could be that my intake came with a filter that was from a bad batch and maybe was not adequately oiled from the filter manufacturer. I also noticed that the new filter has the CTS logo embossed into the black rubber at the end of the filter, where I do not recall the original having this. Maybe they changed filter suppliers altogether.

Not at thus point but will keep an eye on it.

Good to know. I bet you're right and it was just a bad batch of filters

Good point. I think I'll just go with CTS and if I'm too worried about the filter I'll measure and grab one that fits

[jran76]

I think AEM makes a good replacement filter for either if needed (I had the part number somewhere, but can't seem to find it). I didn't have any issues with the CTS filter, and I think the key is keeping it oiled. It may not be the best quality, but I have a hard time believing the Roc-Euro is a lot better. Either way, there are several replacement options for later down the road.

Having installed both, the CTS does do a better job with the tube clearing the coolant line, but overall fitment is so-so because I had issues with the heat shield (I had to modify the mounting points). With that said, as mentioned above and even with the fitment issues I had, the mounting solution for the CTS is far superior to the Roc-Euro both for the heat shield and breather filter.

Both are nearly identical in terms of performance. After going through several intake options, I'd personally recommend splurging on the ECS, but I understand it may not be for everyone.

This sums it up. Also, the CTS intake's heatshield has a lip on the front, which slides into the factory piece nicely.

I was actually looking at the ECS, but I do want the supercharger whine to be obnoxious haha plus it's about $100-150 more. The ECS is probably the best looking of all the available intakes

Quick question before placing an order.. Hypothetically, if my filter degrades in the same manner as @steveyem .. will a warranty/replacement inquiry go through you or CTS?

TIA!

ECS is quieter the Roc or CTS

Yep main reason I'd much prefer the roc euro or cts

I read your other statement wrong, sorry. I have CTS and its nice, wrapped my shield and pipe in heat resistant tape to keep the temps down too.

If you order from us, you would just reach out to us. We can help handle anything like that no problem. But to be honest none of our sales ever had that issue on any CTS intake. Just need to make sure you keep them oiled with proper kits

How'd it work out for you? I'm looking into doing the same

Actually now that I'm thinking about it I may have gotten the idea from you in the first place haha

Agreed, but I would go one step further and inspect the filter for adequate oiling before initial installation. Considering that mine was found to have failed within 1 year of use versus CTS' recommendation of servicing the filter at 18 month intervals, I have to believe there was some defect (possibly dried out from sitting around too long? I don't know) with my filter from the get go.

Two different materials, one big flat piece for the shield and 1 inch wide tape for the tube. The tube was a pain because of the turns but if you take your time it should come out ok.

Yep. I'll definitely inspect the filter before install

Thanks for the tips. Was there any noticeable difference?

The difference in sound is very minimal. As I've said before, if stock is a 1, replacing the intake tube/filter is a 3, ECS is an 8, and RE/CTS is a 9. At the end of the day, the difference in volume is negligible, and the ECS sounds more refined.

[14S4GWM]

I have no logged date but I think others do. It definitely makes a difference. It gets hot as hell under that hood.

Congrats on the new part. Just remember to take care of the intake/ac line (potential) rubbing situation right away. I put about 1,000 miles on my car before I was realized it was happening to me, and there's already some damage.
