TOMEI N2 Oil Block The SR20 engines factory oil block tends to fail due to the weak oil filter sensor screw which often breaks. TOMEI had found the problem during professional racing over a decade ago, so Tomei designed & produced this upgrade oil block which solved the problem. Tomei had later discountinued this product after the end for the N2 series race but due to popular demand Tomei had to bring it back into production with a new revived design. Now being lighter than before with ports for oil temperature and oil pressure sensors.
