How much horsepower can I expect to get from an airbox kit or a set of headers?
A Vararam airbox alone will normally yield an approximate 10+ RWHP gain (on the dyno). Vararam claims up to 40 HP increase through the RPM range. We have found that Vararam shines on the track not the dyno and Vararam proves its value time and time again on the track. A set of Long Tube headers can bring in 25 to 30 RWHP. The combination of the two coupled with ECS tuning usually translates to a solid 35-45 RWHP increase. These mods are often entry level and a great foundation for all of your future performance modifications.
