These are a UK-made version of the high output oil pumps as used in the Royal Enfield Bullet 535 Motorcycle engines. The factory says that these pumps lower the temperature of the head a whopping 30°F. If you install any performance parts or are looking for a little insurance, this is the first thing to buy. They can easily be installed by anyone in 20 minutes.
Kit includes both the pressure and return side pumps and 2 gaskets.
*Fits Iron Barrel 350cc & 500cc models only*
