| This listing is for the stock fuel filter for all z's from 75-83, both non turbo and turbo alike. Fuel filters are extremely important, ESPECIALLY for fuel injected engines. Injectors are very suceptible to plugging so it's critical that you filter the fuel as good as possible. We recommend replacing these filters every 30K miles. These are the best fuel filter on the market today. They use a 1 micron paper inside of them whereas most aftermarkets use a 3 to 4 micron paper. For those of you that don't know, the smaller the number, the smaller the hole in the filter material. In this case, smaller is way better. These are the only filters that we use and install in our shop. These filters fit in the stock filter bracket and also fit the early 80's 200 sx. Last update 03/11 |
