Then all the claims that Bosch, MSD, Mallory, K & N not counting all the other the 100's of companies that have the engineering money are wrong. John, Read again what I said. I did not say that upgrading the air filter to a K&N style unit is bad. Matter of fact, dyno testing on my car showed a 3 hp increase at the rear wheels buy just changing a brand new paper filter with a K&N unit. What I said was that testing has shown me that the stock Delorean air filter housing is an excellent design just as it is, and it does not restrict air flow into the engine. It's design actually helps improve the performance of the engine by directing the air flow and increasing the velocity of the air into the intake. And so far, additional testing of other air filter housings (Volvo's, Renault's and others I've played with, including Casey's design) have not shown any improvements or performance advantages over the original stock Delorean unit. The best performance combination I've found so far is a stock Delorean air filter housing - with the intake tube hooked up like it is supposed to be into the pontoon for cooler outside air - with a K&N filter inside.
