Finished up my air intake setup on my G35 this afternoon after replacing the a/c compressor this morning. A/C clutch coil failed on it after 215K.
I was already running the HPS silicone intake hoses. I ordered a cheap intake setup from Amazon about a year ago but did not like the aluminum tubing and the way they heat soaked. They had terrible transitions and necked down the MAF sensor openings to about 2.25" which is smaller than the factory MAF housing. Car ran well but ran rich on the stock tune. I had pulled them off and put the stock air boxes on with K&Ns. I finally got the itch to let the VQ V6 have that awesome intake howl they have. I ordered a pair of 2.75" MAF housings about 3 months ago that were finally delivered this morning. I used the heat shields and filters from the cheap intake kit. I fitted it all up. Have a little tuning to do on the MAF tables but it runs very well. Fuel trims are running about +10 to +14 at the moment. Have not been WOT but the car accelerates much more smoothly now. I love the way this little high reving 6 sounds. It has equal length headers, high flow cats, 2.5" custom built exhaust with a X-pipe and 4 magnaflow mufflers into 4" tips. Quiet when you are cruising along but really opens up when you get into the throttle. Cruising around town checking out the a/c repair this evening it was knocking on 20 mpg. I even ran it up to 5,000 rpm a couple of times in 1st and 2nd gear at about 1/2 throttle leaving a couple of traffic lights. Not bad for a ~380 hp V6 with a 5spd auto and 3.91 gears in a heavy 4 door sedan.
A/C repair was a complete success. With an Oreilly's Murray reman compressor and charged with R152a it is cooling down to 34°F with the a/c fan on high speed and the climate control temp set to 60°F. It will freeze you out of the car after 5-10 minutes. Compressor is running quietly too. Much quieter than the 215K mile one even though it too was still blowing ice cold up until the clutch coil failed. Thats with a 25% underdrive crank pulley as well.
