Some bloke yesterday said that rubber taking air to the t/b and better for preformance than the s/steel ones as they deliver cooler air true or false :confused:

i should imagine there is pros and cons with either after years of uses the rubber ones become brittle and crack causing erratic idle problems/boost leaks

 

but overall i would say false to your question air flows through at an almost constant rate,so air would still remain pretty much the same
