These aftermarket air filters biggest benefits are easier access to idle speed & mixture adjustments. I think performance improvement is negligible, it has been debated on other threads. Weight savings may be three pounds.
I used a hacksaw and cut out a large section across the hinged lid on my stock air filter housing. This retains the use of the stock Mahle filter. The sharp edges were turned in and adjusted to not interfere with the A/C hoses.
