In Reply to: are using a stock 2.3 litre for the dyno run and posted by troy on September 17, 2000 at 18:39:36:
The assembly utilizes a KN type performance air filter and a two piece aluminum housing. It includes a black wrinkle finish cover plate and all hardware. It is a bolt in/on unit that will take only 15 to 20 minutes to install.
The unit was tested against an evo air filter assembly and on the chassis dyno and realized a 4.4 to 4.8 HP gain @ 6100 rpm! I have included a link to the dyno chart for your inquiring minds.
The unit is priced at $250.00 + shipping.
