When it comes to your bottom line, every ounce of fuel economy you can get out of your Paccar is critical, and some extra horsepower to pull those grades easier is icing on the cake. Upgrade your exhaust manifold for improvements in both areas.
- High tolerance press fit connections resulting in a leak free connection ensuring all exhaust gases are being delivered to the turbo to get the most efficiency and power out of the engine. No cracking, no leaking, no warping.
