    Stock airbox ridges

    If I'm not going to be getting a lid for a while and am doing the FRA mod anyway, should I just take the extra time to shave the ridges out of the airbox?

    Pros/cons?

    I only found one post even mentioning it which is probably because everyone just buys a lid but I'm curious as I plan to be as cheap as possible for quite a while.

    Thanks,
    Erik

    You can do it if you want, but it would only be a 1-2 hp gain because the problem with the stock lid is the oval transition piece. That is where you lose horespower.

    I don't think you'll see any noticeable gains at all. Not worth your time.
    Watch the for sale forums here, LS1Tech, other forums, & watch eBay. You can find used lids for half-price of new. Sometimes better. Be patient & keep watching.

    I agree, not worth your time.
