The world famous “HEPOLITE” brand with their distinctive yellow and black packaging has announced plans to compliment their recently relaunched piston range with a range of Original Equipment specification piston rings.

The Hepolite brand has a long history of producing engine components and is well known for engine parts for many classic British vehicles, many of whom were supplied as OE with Hepolite branded piston, rings & bearings.

Paul Grosvenor, who has held positions at piston manufacturers including MAHLE & Kolbenschmidt and who is now responsible for the Hepolite product range comments “We have received a tremendous response to the relaunch of HEPOLITE pistons and many of our customers have requested that we develop the range with additional products. Piston rings is the first of these new products. Initially we will concentrate the range on premium material parts such as steel nitrided and DLC coated ring sets as well as applications where we feel we can add a higher value option to other suppliers in the market”

The initial range consists of rings sets not only for older vehicles, but also modern high-performance vehicles such as BMW M3 & M5 which use the BMW S65 V8 and S85 V10 engines. Grosvenor continued “The high-performance road car market is particularly buoyant at the moment, and many of these vehicles are either being used on the track in one make race series or as track day vehicle. Many of the well-known manufacturers are not only slow to respond to the demands in the market for these parts, but when they do the price level is very often close to that of OEM parts. With our HEPOLITE brand, when plan to offer parts that are competitively priced against OEM and established aftermarket brands with no compromise on quality or specification”.

All HEPOLITE parts are manufactured in world class facilities that are not only certified to international quality standards, but are also producing for global vehicle OEMS. Grosvenor comments “Quality is always the main point and one area where we will not compromise with the HEPOLITE brand. In fact, many of our parts are an upgraded specification when compared to other brands and OEM. For example, our BMW S65 / S85 rings use a ductile iron second rings to improve performance, our competitors are using cast iron and on other parts we have specified steel nitrided rings rather than chrome plated cast”.






Adding to our already impressive range of forged pistons & complimentary products, the Wiseco range of forged pistons include a large range of “off the shelf” pistons for many of the most popular engines in the UK and Europe. MAR Motorsport are proud to be an official distributor for the full range of Wiseco Automotive products, with the two companies sharing a passion for high quality products and innovation.

Wiseco leads the performance aftermarket by producing the highest quality forged pistons for domestic automobiles, sport compact and racing applications right here in the USA. Wiseco is unique because we forge all of our own pistons in house, and produce all of our own forge tooling right here in the USA. This allows us to control all aspects of our manufacturing process from raw bar to skirt coating finished parts.In addition, in-house dyno testing gives Wiseco the ability to develop state-of-the-art technology such as new shapes, coatings, and components, and lead the industry through rigorous R&D.

Linking all segments of Wiseco’s organization through design, testing, manufacturing, and distribution allows us to fulfill market needs with minimum lead-times.Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance.

Available exclusively from MAR Motorsport, piston rings for MK1 Focus RS 2.0 Turbo

Traditionally piston rings for the MK1 Focus RS have been unavailable as separate items, the only option was to replace the complete piston. We have worked directly with MAHLE, the Original Equipment supplier of the pistons and piston rings for this engine to Ford, to secure supply of replacement piston rings at standard bore size of 84.80mm.

These MAHLE piston rings are a direct replacement for the rings used on the original MAHLE pistons in the Ford Focus MK1 RS with the 2.0l turbo charged Zetec engine, engine code HMDA. These replacement parts are identical in every way to the rings fitted to the pistons when the vehicle left the Ford factory. This means not only can these engines now be overhauled cost effectively, but they can also be overhauled using parts in identical quality to the original.

The specification of the piston rings is as follows:

Bore (Ø)

Ring 1
1.50mm, Retangular ring, PVD coated

Ring 2
1.50mm, Taper faced napier ring, Phosphated

Oil Ring
2.00mm, Coil spring bevelled edge, Nitrided


These new range additions complement the range of Original Quality engine parts that are already available for the MK1 RS Focus. For further information on our range of parts for this engine then please Contact Us
