FOCUS RS RODS AND PISTONS
£840 (PISTONS) £1399 (RODS)
Mountune have really gone to town with the Mk3 Focus RS, and their latest offerings for the 2.3-litre EcoBoost engine are far from simple bolt- on upgrades. Instead, they’ve turned their attention to sorting out the engine’s internals with these new forged con-rods and forged pistons, ready for some serious bhp increases!
The con-rods utilise an I-beam design with extensive machining to optimise weight without reducing the rod’s strength. All edges are radiused to improve durability, and they feature precision-machined tangs to securely locate rod bearings. They also come with low friction silicone/bronze pin bushings ideal for high rpm applications.
The pistons boast an enlarged 23mm gudgeon pin, to address a known area of weakness, and are actually manufactured in the USA by Mahle Motorsport, using their 4032 grade alloy. The pistons also feature the latest antifriction and grey phosphate coatings to reduce drag, wear, noise, and to prevent against micro-welding and pin galling.
