I sent an inquiry to Spectre regarding performance improvements using the Muscle Car Cold Air Intake, reply below:
" Through our testing, we have found gains of 1.5 - 2.0% for every 10deg or so the intake temperature is reduced. The latest car that we have tested on the dyno with a Muscle Car Cold Air Intake was a 1970 Chevrolet Camaro with a 383CI. The kit gave us close to a 20HP difference, when compared to the stock setup sucking in hot under hood air. We do not have any published data to send you, as of yet. We are still going over all of our numbers and trying to get them in a readable format, which we can release to the public. I hope that this answers your questions. If you have any further questions or comments, then please feel free to shoot me an email at
georgel@spectreperformance.com or give me a call at (800)-821-4868 ext 336 "
