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.
