Air box vents

[AdamVZ89]

I put a couple 1" round Uni airbox vents in. What do you guys think?

First gen Apes ran pretty rich, you can likely add quite a few more to lean out the afr closer to the sweet spot.

You should add 4-5 more per side to do any good. Did it to 2 of my sleds.

I had the Fix ramair lid on mine. I saw minor gains and substantially more noise. Like the others said, you're going to have to add several more if additional performance is the goal.

Yes, it will be louder.

I have had 4 per side on my 12 for 21,000 miles, works awesome!

Ran a ram air box mod and a complete Excel exhaust system on my 07. Saw the most gains I saw was in noise. Removed it all and went back to stock exhaust and airbox. The Dream-0-Meter top speed was exactly the same. Its like flipping the air cleaner lid on your quadra-jet.

I used to flip the air cleaner lid on my 400ci Pontiac powered Trans Am. It was good for a solid 15hp gain!
Just ask me!
