OK, I know I'm new to this and p r e t t y s l o w.... but I just gotta know what I should do for a bigger air filter. I take it from reading some posts that a BHAF is an after-market, much bigger air filter. This allows more air into the turbo, thus increasing output and reducing fuel mileage. Am I on the right track?

So, if thats the case, what BHAF should I look at, and how much? Is the BHAF an interior filter (i.e. is it housed inside an air filter housing), or is it external of a hard air filter housing?

PS. New clutch just cost me $700. Thats the LUK Pro Gold Series clutch and a new flywheel.... A friend and I are installing it on Friday. Wish us luck!!!

There is only one "BHAF" filter. It's actually a big rig paper filter which has a lot more area than the stock filter. It allows the turbo to breathe better, but its affects aren't noticed until you start developing serious HP. It does however let the turbo whine out which is why I use one for my "sheep in wolf's clothing" ride. Check the FAQ section for filter numbers.

So do you have to do any modifications to install one of these filters? Lets say I wanted to go with the NAPA filter. What would I have to do to fit it on?

Remove the stock air box and attach the hose to the end of the filter is about it. There's a pattern, I think also in the FAQ section, for a heat shield that you can make to shield it from the engine heat a bit. Not required, but might be helpful.

it will not reduce your fuel mileage, but im betting $20 you already knew that and the above was a typing error

Actually, it does a little bit.
You can hear the turbo more, so you tend to have a heavy foot to produce more and more turbo noise.

After a couple months, it wears off, and mileage returns to normal.

The filters themselves are/should be waterproof. I had a 2818 Baldwin on my PSD and it was waterproof. The filtering media is more advanced in the better filters over a paper filter. The higher cost is evened out by a longer service life.
