B18 and B20 engines call for "100 octane leaded" fuel, but this hasn't been available for quite a while. Tuning one of these engines to run on the low octane stuff they call gasoline can be tricky at best. Installing a low compression kit will help prevent pinging and other problems associated with low grade fuel and high compression.
Kit includes a thicker OEM headgasket and matching water pump seals.
Not for use with fuel injected cylinder heads. This kit typically lowers the compression ratio by 1 full point.
