Hi guys I'm new to the forum but as my first post I was wonderng if anyone has any experience in the EVO highflow intake system. They say that it can put on 8 HP more with it. However, I also heard it might cause check engine light problem. Could anyone give me some advice? Thank you very much.

I have one in my car. It did set a CEL. I cleaned my MAF carefully with electrical cleaner, cleaned and re-oiled the filter lightly and have not had problems for the last 2 years.

Thanks a lot Graeme. Where did you have it installed? Can I have it installed at the Porsche dealer here since I don't know any distributor for EVO here in Portland? How long does it take to have it installed? How about its performance?Thanks.

Mine was a DIY install, took about 3 hours. I'd recommend an independent shop over a dealer for installation.

I installed it after I had a custom exhaust fitted so I don't have an intake only number, but the combination of my custom exhaust and EVO intake netted 7rwhp.

If you're not a DIYer, give Steve Weiner at Rennsport Systems a call. I think his shop is in Tualitan but I could be wrong. I have the Evo system on my race car. I'm a little sceptical that it actually adds any hp but I haven't done a before and after dyno so I don't know for sure.

I should point out that before I installed the EVO intake, I actually LOST 9rwhp by installing the exhaust :oops:

Adding the EVO intake gained back my lost 9hp and added a few more. the interesting thing about the combination of exhaust and intake wasn't so much the extra peak hp, but was the additional hp at the upper revs, the car just kept on pulling rather than running out of breath.

My exhaust is for sale...$300...

Since you are selling the homemade bi-mufflers, did you put back the OEM muffler??. If so are you going to dyno it?

Unfortunately, Outlaw Performance who I dyno'ed with have gone out of business :(

You can't directly compare results from different dyno's so there is little point. ;)

C'est la vie!
