For all you boys that have the SLP airbox...is it a noticeable gain, or does it just look perdy? Because I might get one.

airbox???wth...why not a cold air intake?? or is it a ls1 and u have a lid?

Pretty much all lids give the same gains, within 2hp of each other. I think the MTI clear lids look the coolest. But I heard that the fitment was junk though. SLP's has a tight fit though. GM High Tech did a dyno/track test of most of the lids on the market. All performed about the same.

thank you

Find the cheapest one you can :2cents:

Hint: its not SLP
