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 billet aluminum.

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 direct port parts only, to be used with your existing methanol injection Controller and tank setup. **Our BimmerBoi Performance Shop car will be running this kit Paired with the tank and controller found in the description of our install guide here**

*Please note, all PI plates be it standard PI or our Methanol PI offering move the intake manifold out of reach of the stock charge pipe, you will need an aftermarket offering like the product listed here*

Nozzle Size Guide:


Stock turbo - CM2 port + CM7 charge pipe
