Installed EVO Intake, Holy Crap!

[easyc]

That x51 intake manifold will not fit on a 3.2 block and probably not a 2.7 either... different bolt pattern...... also that TB part number may or may not be correct for your setup... the 986 and 996 car's TB have a different bolt pattern than the 987 and 997 cars as well.....also porsche has identical part numbers for different size and pattern TB's..... been through all of that with my swap!!!!!!!

Sorry for being so harsh. I just found out someone installed a "hot air kit" on my brothers Boxster before he bought it. Why would you do a K+N snorkel in the engine compartment of a Boxster?? when STOCK it pulls fresh air from outside?? WTF??

Hi, that is exactly what i was thinking how do you get cold air from an oven
Can we install a 12 volt cooler in the trunk and plug the evo intake tube to that
would make a lot more donkey power

Real live engineering data says the actual inlets on the side of the Boxster are TOO LOW. If Porsche had moved them up on the sides of the car, they would actually flow more than the 50% they flow now.

Engineering buddy of mine designs cars for VW/Audi and sits in an office next to the guy who designed the Boxster We hold some interesting conversations to say the least!!

The EVO intake does draw from the outside. It comes with a surround so that it won't suck hot air from inside the engine. I did mine and love the results. Besides, I needed to replace the pipe that the MAF was installed on anyways so it was worth while. Great sound too (especially combined with the PSE).

I just tore out my old air box. I figured that if I ever want to go stock again I'll just order one up from a dismantler.

i'm very happy with the EVO airbox. stock airbox came out fine in one piece with a bit of patience. didn't lower the engine mount either.

only two sore-spots are the broken plastic tab on the intake vent cover when it was pulled off and the CEL that came on right after the instal (pulled the MAF sensor and cleaned it and CEL went and stayed off). the tab is still broken but the vent stays put ok.

engine pulls smoother through the rev range with a small but noticeable drop in low rpm power and a significant and VERY noticeable increase in high rpm power. and the sound is pure magic.
