ATTENTION
Before you can continue, you must agree to all of the following terms:
The RM Series is comprised of a damper cartridge secured within a threaded outer body. This specific design requires a lubricating grease to be applied during the assembly process between the two damper and threaded body to avoid metal-to-metal contact. In order to keep the two components from touching each other and generating noise transmission you will need to periodically clean out the old grease and apply new grease.
This is a simple process that can be done with just a few common tools. It does not require you to open the internals of the dampers themselves and therefore you do not need to have the dampers re-pressurized after carrying out this procedure. Please contact us on info@mlperformance.co.uk for more information and a step-by-step guide on how to complete this maintenance.
As a result of this required maintenance, we do not recommend the RM Series for road use over the BR Series or ER Series.

As part of our expanding Mk4 Focus ST product range, AIRTEC Motorsport is proud to launch our oil catch can upgrade suitable for track or fast road use.
Oil catch cans are vital preventative additions to ensure the performance and efficiency of Direct Injection engines doesnt deteriorate over time.
AIRTEC Motorsports solution to developing a catch can kit specifically for the Focus Mk4 utilises the available space to integrate seamlessly within the engine bay. It features a unique high-quality billet-machined bracket, finished in powder-coated matte black, which allows the catch can to attach neatly in place.
The can itself features an internal baffle and dipstick, which detaches to allow easy maintenance. It comes with a comprehensive fitting kit that includes all fixtures and fittings, as well as a detailed installation guide.
Why do I need a catch can?
The original oil breather set up can cause issues with carbon build-up inside the engines intake system over time. It forms an oily sludge that covers parts of the intake and inlet valves, which reduces air flow and therefore performance and efficiency.
Once the build-up has formed, its a costly process to clean, so it makes sense to take preventative measures in order to avoid carbon build-up forming. A catch can also filters harmful contaminants before they can reach the inlet system.
Please note: DOES NOT FIT LEFT HAND DRIVE MODELS.
