Product Reviews      Review part RU-1785

 I used a pair of these filters (RU-1785) for my new 451 cubic inch LS engine that is now in my 2002 Z06 Corvette.  During engine dynamometer testing we could not find any power loss when these filter were installed versus a bare 102 mm throttle body.

Great work.
