YB Cosworth WRC / Long Rod Pistons


Now Available

Forged IAPEL pistons for the legendary Ford / Cosworth YB Engine.

Manufactured exclusively for MAR Motorsport by the leading producer of forged pistons in South America. IAPEL are active in many forms of motorsport. From wins in all classes in the Turismo Carretera, to dirt bikes to factory supply to rally teams. IAPEL pistons are also used extensively in drag racing, with sub 2 litre 4 cylinder engines producing over 1,000 HP!

These parts are designed for the WRC or 136mm long rod engine configuration. Complete with valve pockets, they are also suitable for machining custom bowl designs. Unlike many forged pistons, these parts are dual coated fro friction reduction (hence their non shiny appearance). They are supplied complete with NPR Japanese steel nitrided rings, which are an upgrade from the standard MAHLE design.

Available in 91.33mm bore size, these pistons are designed for high power YB engines, with none of the weaknesses of the standard MAHLE part.
