CPR6 manifolds: Click images to enlarge

Using our years of experience in flow-bench technology, the CPR6 allows your engine to breathe better, producing better horsepower while actually returning better fuel consumption figures as well.

Or you can try any of a dozen combinations of add-on parts and still be assured that our manifold will increase the power by the same amount regardless. If you've already got a better exhaust, our 20hp goes on top of that.

On a standard engine in the family VE sedan, the modified manifold returns 8.6l/100km which helps the family budget. Best of all, you can unbolt it if you sell the car and fit it to your next alloytec.

Bolt on & enjoy!
