Has anyone seen an increase in HP or MPG with their aftermarket filter system? if so, what increase(or decrease) and what product? Thanks!

i installed a K&N air intake and a magnaflow muffler and my gas milage went up from around 17 to around 20 on a stock 06 renny....

how much did you pay for all that? did you do it yourself?

since this is in the 4x4 section, just remember if you wheel in water or mud, that an open filter (like a K&N cone, etc) are not great for that

i would keep a closed intake filter system ...

I have a rusty's air tube with a true flow cone and it is awsome.I had a k-n befor the true flow but the true flow suck's alot more air and sound's really cool.

I have the rusty's air tube and a 6x9 K&N cone, I didn't see an increase in MPG so much as a better average when I lead footed it. Plus it sounds cool

I put in the K&N FIPK. Easy install. Extra 1.5 to 2 mpg

I bought a cheap air intake off of e-bay and then replaced the filter with a 6x9 K&N. I also replaced the stock muffler with a Magnaflow.

I have a picture of my air intake on my cardomain site.

I notice a performance increase, not sure on MPG.

I also added an Ebay dual air intake, i went from 16.8 to 18.7. not too bad, that was lost when i got the MTR's.

Only intake change I heard of that has been positive in the mpg while not causing worry when in mud and water was the snorkle like the aussies already have

i found the k&N intake on ebay for about 200... and the magnaflow muffler i ordered from rusty's for $79... both were really easy to install.. the muffler came with an extention which worked out perfectly... all you need is a sawsall and i welded it.. but it did come with clamps that would work... im working on getting a decent video of it to post for the sound.. but havnt had time yet
