has anybody heard of professional products and are they any good rpm outlet has plenum for $109.00 but i have never heard of them.

 

Ive heard mixed things. Some say the quality isnt that great, like, you should clean up the casting a little, but who knows. Id go for a C&L for the extra 40 bucks I think. Or go for a used combo of accufab, they can be found for about 300.

 

get an accufab plenum with a 70mm throttle body
