Re: Engine Mods
I wasnt buying them to increase anything. Mainly cosmetic. Wanted to have a nice soound to the h3 and allow more air to the engine. So anyone who has made these mods give me insight?

Re: Engine Mods
Do a little research on K&N filters and decide if lowering your filtering efficiency for absolutely no gain in power is worth it.

Re: Engine Mods
I've had the K&N on past trucks and just ordered it for this one. There are plenty of people that think they are bad but it you keep them cleaned they are fine. And don't over oil them.
I have a Gibson catback also. I didn't notice any power improvement, but I'm sure it helps a little. It's noisier then stock, but not to much. Almost a little to ricey for my taste, though. I wouldn't mind trying something else.
I got a pcm tune and I did notice the power gain on that one.
All together the truck is noticeable faster.

Re: Engine Mods
Don't you think if there were any quick and easy wasy to get more MPG and performance out of the I-5 the GM enginers would have done it?
