This is our extra large universal carbon fiber airbox kit to suit 4 cylinder engines. The airbox comes with a 6"/152mm inlet and carries 14 litre's of air. Backplates are available in flat, 30 and 60mm increments to further increase volume with the 30mm tested to increase the volume of air available 1.5L to 15.5L.
Initially designed to maximise capacity in a 190e with the 2.3 and 2.5 M102 16v (Inc Evo/Evolution 1/2 models) engines with our ITB kit, but the removable backplate enables fitment to any engine bay that can fit the size.
Dimensions are 520mm long, but 200mm tall and 190mm wide, which can be made 220 or 250mm if there is space.

This is our road going twin 230mm clutch setup to suit the Mercedes AMG M113k 5.5 Kompressor engines found in the W211 E55, R230 SL55, W221 S55 and C215 CL55 AMG cars. This kit will hold 1200NM of torque whilst retaining OEM drivability.
The flywheel is a dual to single mass conversion, CNC machined from a forged billet of chromoly steel to retain the OEM starter motor and 60-2 timing gear. Weight has been lowered when compared to any OEM dual mass unit reducing inertia for ...an improved response.
The clutch cover has been machined from a billet of aluminium with chromoly pressure and intermediate plates. Twin friction discs have heavy duty organic linings for improved thermal input with the first disc coming mounted and pre aligned. The kit is also available with cerametallic linings and can be made for nearly any engine and gearbox combination. M104 to 6 speed is next in development.

Apologies for the quiet social media run. We've been very busy on some projects (some of which we aren't able to share) and new developments which we'll bring to you soon.
In the meantime, if you're struggling to work out which gearbox and flywheel setup you need to convert your Mercedes or AMG to manual, we can help source a package to suit your needs and ship worldwide. If you have a project in mind, send us a message.
