all valid points but the air tec stuff gets a rely bad rap for a procuct that dose very well. the results should be on www.autospecialists.co.uk somewhere, the only cars that i no have def been tested are a standard FRST and standard ERST and my RST (190bhp)

dropped temsp massively on my car even on a massively heat soaked engine ( done lik 7 runs on the day lol)
