We all love boost, and we all know that more boost equals more power, however we also need that boost to be cool in order to be effective. To truly maximize the performance of you Forester or WRX we need to get rid of that tiny intercooler sitting on top of the engine. Going with a larger and more efficient Killer B Aftercooler will keep the charge temps down which will not only allow you to run more boost, but will also give you more reliability. That’s right, hot air entering the engine can lead to its untimely death, so give your engine the opportunity to reliably make the power it dreams of with the Killer B Intercooler.

Made in the USA and 100% in house, the skilled Killer B fabricators hand Tig weld and quality check each and every intercooler ensuring that it can handle in excess of 575WHP, along with a Lifetime Warranty means this may be the last intercooler you will ever have to purchase.
