Original price £1,377.63

Williams Performance & Cobb Developments have worked together designing this direct port meth kit for the BMW/Toyota B58 engine. This injection plate is CNC machined in the UK from aluminium billet.

Using direct port injection will give you even fuel distribution across all the cylinders in your engine, unlike charge pipe injection only which 'can' cause some cylinders to run lean resulting in catastrophic engine failure.

This kit will also hugely increase the amount of fuel you can supply your engine with giving you the ability to safely produce a LOT of power.

This kit is the COMPLETE direct port methanol injection package, which includes EVERYTHING you need to run direct port meth on your B58.

We offer this kit with various size nozzles and also the option of 1 charge pipe injector to aid IAT suppression.

Please see our other listings for various tanks. We'd advise nothing smaller than a 2.5 gallon tank to avoid it running out too quickly.
