Weapon R used my xB2 to prototype a cold air secret weapon intake. OMG! The difference is like night and day, you feel the car pull much stronger and the performance gains are phenomenal. Ive yet to feel this significant of a change even with the header and exhaust combo. They say that full production will be underway in a week and finished products should be here in about a month and a half. But WOW.. I really have to say Im very impressed. I should have dyno numbers next week for you guys, but they showed me something that was impressive. They took a TC with Fujita cold air intake on it, took the Fujita filter off and added their filter and the car dynoed with 6HP more!!! So you now you figure in the secret weapon piping, plus cold air, and their filter I should be looking at a total of 10+ hp gain.. thats quite a bit for a 160hp stock motor.
