This downpipe optimizes turbocharger spool by enabling faster exhaust gas evacuation while maintaining emissions compliance under federal EPA standards (except California). It supports forced induction setups without sacrificing engine performance or triggering emissions warnings.

Note: Not legal for use in California per state vehicle code sections 27156 and 38391. Federal law prohibits tampering with emissions control devices; this part meets EPA standards for aftermarket repair or replacement.

Worth it if you dont want your oil cap to get damaged.
Color: Black
I used to use a regular filter clamp form by oil filter cap and it was damaging it. I bought this and it was definitely worth it. If anyone is wondering I have a 2007 bmw 335i e93 and it was a perfect fit.

Actually works on BMW!
I purchased this after the shorter black fluted tool I bought last year failed me. This thing is way better constructed, fits perfect , and actually works to turn it after you can’t turn it by hand any further. Was able to get torqued down to 25nm no problem finally with ease!
