AIRTEC TWO-PIECE BREATHER SYSTEM – MK2 ST & RS
Upgrade your Focus ST/RS Mk2 with the AIRTEC TWO-PIECE BREATHER SYSTEM – MK2 ST & RS. Tuning levels on the Focus RS & ST have pushed the standard Ford oil filter housing to its limit. The fragile diaphragm inside these housings can split or leak due to the clip-on design, necessitating an upgraded breather system. The AIRTEC Motorsport two-piece breather kit is the perfect solution.
Included in the kit:
- Modified & Baffled Ford oil filter housing, complete with new oil filter element and oil seals for hassle-free fitting.
- AIRTEC Motorsport oil separator with billet mounting block and laser-cut fitting washer. It also serves as a template when drilling to attach the separator to the battery tray.
- Pro Hoses oil-resistant fluoro silicone lined hoses, custom-made to fit your engine bay. These provide a superior fit compared to straight hoses and come with full stainless steel jubilee clips. Some minor hose trimming may be necessary.
Exchange: We require your old oil filter housing before sending the two-piece breather kit. Once purchased, a kit will be allocated for you. Upon receiving your old Ford oil filter housing, we can dispatch your new two-piece breather kit.
Outright: You will receive the full kit. If you wish to return your old oil filter housing, we will refund you the surcharge. This option is convenient for international customers who can’t send back their old unit and for those who prefer to fit the new kit before returning the old housing after installation.
Please note that our kit is designed to improve engine breathing by venting fumes to the atmosphere. In contrast, the engine’s original breather system limits fumes by recirculating them back into the engine’s intake for consumption.
However, enhancing the engine’s breathing capacity may reveal previously unnoticed issues, typically indicating engine wear or general health concerns that were previously masked by the original breather system’s limitations.
While we’ve sold hundreds of these kits over the years, it’s crucial to emphasize the importance of ensuring the engine is in excellent health and running order. Occasionally, a customer may report experiencing a noticeable increase in fumes and/or smoke after fitting a breather kit, particularly as these cars age.Read More
