cold air intake?? exhaust?? whats the deal - 4/5/2008 2:30:39 PM    86gs700e   Posts: 3 Joined: 2/18/2008 Status: offline Okay.  Heres the deal.  I have always heard alot of good things about K&N air filters and accessories.  I recently bought a 1995 z71 with the 5.7, and 11 miles to the gallon isn't really ideal.  So I asked some buddies, and some said get a cold air intake.  So I look around on this site, and quite a bit of people do not seem to think that a cold air intake will do anything.  Others go as far to say that K&N air filters/intakes are bad for motors.  Will a cold air intake do anything for gas mileage??  Would exhaust do more?? And if a cold air intake, is K&N a bad choice?? There are so many varying opinions, and I can't seem to make up my mind which is correct.  Thanks Post #: 1

As 95k1500z71 said, cold air is more dense than hot air, meaning more air is entering the intake when its cold, the vehicles computer tries to acomplish an air\fuel ratio of 14.7:1. So if more air is entering the intake, the computer will add more fuel to keep the ratio correct. (in reply to 95k1500z71) Post #: 3

Everyone check this site out about filters and their ratings. I know that these ratings are produced by S&B filters, but they not only compare S&B to other products, they also give the ratings for the others compared to stock. http://www.thetruthaboutfilters.com/ _____________________________ '95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.

I've seen independant tests where the K&N's leave all others for dead. The main problem is people over oil them which ends up on the tiny wires/resistors in the MAF. I don't think you'll see ANY difference from the K&N except you won't ever need to replace it...just wash and re-oil. I'd suspect the guys who've seen an improvement have seen it from the exhaust mods. _____________________________ Regards Howard (in reply to northey87) Post #: 8

Maintained properly an S&B will last a lifetime, like K&N. _____________________________ '95 1500 Silverado, 350, flowmaster Force II exhuast, S&B CAI.
