Here we have the long awaited Jadus Oil Filter Cover Cooler! This amazing piece of kit is CNC machined from billet 6061 grade aluminium for excellent heat dissipation characteristics and strong mechanical properties, then anodized in black. After CAD simulations and real-world testing, we can proudly say that this completely bolt on kit not only looks fantastic, but also reduces oil temperatures by 3-5 degrees C* in comparison to the stock cover. How does it work? The cover increases oil capacity by 100mL and cooling surface area by over 400% compared to stock. The oil from the engine's sump is routed as per usual, but then it takes a short detour through the cover and stainless adaptor, before it makes it's way up to the cylinder head where it showers the cam, rockers and valves, with oil at its optimum operating temperature.
The cover fits the following Yamaha models:
SR250 XT250 TT250 SR500 XT500 TT500 SR400 SRX600 XT600 (some model years)
Direct bolt on replacement for Yamaha part number: 2J21344700
*(measured just after the oil passes through the filter assembly)
