Thanks man. These forums and members like you have given me some good threads to research and know what to look for. The one thing about these pipes is they do heat soak considerably. So OP should look out for that. I installed the honeycomb grille to help reduce this a decent amount, but it’s not gonna be as effective as a PRL cobra or something similar. These damn cars get so hot.Nice looking intake! Glad you enjoy it and it's working out for you.
Thanks for posting this man! Finally got around to a data log. Update: did a 3rd gear WOT pull. Here is the highest the fuel trims got and this log shows at 6k RPM. STFT 3 and LTFT -3.. intake was only 8 degrees over ambient. Pretty damn good if I say so myself. Idling my STFT is about 4 and my LTFT is about -3I’m not OP but I decided to test mine, which I haven’t done for awhile so it was a good time.
I found that my STFL and LTFT were typically +6% to +8% at idle.
In driving conditions they never exceeded +14% and that was under heavy throttle. This snap is the closest I could get while my scanner still had the driving data up.
At cruising speed my trims were dead even. My IAT2 is about 13 degrees over ambient and that’s with my car sitting in the hot driveway all day.
As the data shows, the intake is keeping fuel trims pretty well within tolerance and keeping internal temps down, confirming these pipes and a quality filter do work.
Full disclosure, I also have aftermarket coil packs as you can see on the first page. This may vary my results.
Good to see this! My trims are reasonably different, but I remembered I’m running a little E-85 in the tank. I’m likely really close to 0 on my trims if I run just 93 like I normally do. We can officially close this case as the eBay pipes being perfectly safe.Thanks for posting this man! Finally got around to a data log. Update: did a 3rd gear WOT pull.

Yeah I agree. I only drive the car about 200 miles a month now so I don’t really get to experience the new intake. But thought I needed to shut some ignorant people up on the forums lol. I drove 50 miles yesterday in traffic and in boost a lot on the highway and the pipe was hot. But cruising around town it feels barely even warm.Good to see this!

What I’m looking to do now is improve the heat resistance because I’ve noticed the pipes get heat soaked bad once the car stops moving. I don’t want to wrap them, so I’m looking into thermal barrier coating. I for sure want to get an intercooler too. That also heat soaks and limits the effectiveness of any CAI.
