The deed is done. Not hard at all. I only have 4 torx screws per side. The original filters were not too bad but one side seemed to have more sand and dirt than the other. Cleaned up the place where the filters live and schlept it back together no problemo. To tell you the truth I may or may not notice a difference because the bat-mbile is so new to me. But I might get some indication of better mileage as I did record that for the first thousand miles.

I never saw so many spark plugs living in one engine...this thing is just a joy to own...

Thanx a bunch for the information troops...popeye
