| This tune up kit is something that we put together for our customers. It includes: 1 YEC or Diachi distributor cap, 1 same brand distributor rotor, 1 Nissan PCV valve, 6 NGK spark plugs, 1 Factory Nissan fuel filter, 1 Nippon air filter. The cap, rotor, and air filter are all made by the same companies that make these parts for Nissan. We recommend a tune up every 30K miles, and an injector clean as well, to get your zx running great. If you would like a set of NGK spark plug wires to go with your tune up kit, that must be purchased separately, see listing. The NGK wires should last you at least 150K miles on the 300 zx, although we've seen them go as high as 250K miles. Most other plug wires only last 30K to 60K miles. NGK wires are the best on the market today. Last update 03/09 |
