Tomei began operations in 1968 as a race car tuner in Japan. Over the last 40 years Japan has emerged as one of the leaders in automotive research, racing, and culture. Tomei products have been utilized in nearly every motor sport imaginable. Tomei’s racing heritage means their research and design team have first hand knowledge of the extreme demands racing puts on an engine. Using only the highest quality materials means that Tomei’s products can handle the intense strain and heat a purpose built engine will experience whether it be on the street or the track. Tomei’s attention to detail is second to none. All of their products are thoroughly researched and engineered to achieve optimal efficiency. Because of even miniscule differences in measurements can cause catastrophic engine failure, all Tomei products fall within strict tolerances. Tomei machines all of their engine components to enhance airflow and ensure proper fitment and seal.

The SR20 engine's oil block tends to fail due to the weak oil filter sensor screw which oftens breaks. We at TOMEI had found the problem while we were competing in professional N2 race series over 10 years ago. So we designed this upgraded product which solved the problem. THis was later discountined but due to it's extremely popular demand we decided to re-release this product with a new design. Now lighter than ever before and has the ports for the original OEM sensors for direct fitting as well. The failure of your oil block can lead to disasterous results with terminal engine failure. With all the time and money spent on your race engine this is an absolute must have upgrade to protect your investment. Especially with engines running a sandwhich plate or similar oil cooler this is an essential safety precaution.

Please Note: Kit does not include Oil filter adapter, hoses, or oil cooler**

    Good quality part, pleasing to look at the machining as well; as you would expect from Tomei!
    If you want to run different sized AN fittings, the Tomei oil block itself is threaded for M18x1.5 threads.
    Enjuku was good again on this product with fast order processing and shipping.
