Temporarily Unavailable: Unfortunately, the air filter used in this kit currently out of production, and will be unavailable until further notice. We are looking into alternative options for stock type filters, and hope to have something available soon. Thank you for your understanding.

Click on the items in the list below for the individual components included in this kit. Air filter options are currently limited; however, performance air cleaners and K&N drop-in style filters are still available (see Related Items).

NGK has upgraded their original application for the included Spark Plugs with Resistor technology. Non-resistor plugs not only interfere with your radio, they can also interfere with electronic ignition signals, so this switch to Resistor type plugs can only benefit your Z's operation. Also, this upgrade did not increase the price of the kit!

Restore your Z's performance!
Tune ups are an important part of the general maintenance of your Z. The metal parts of the spark plugs, cap, rotor, and points all wear down over time from heat caused by repeated use. This can lead to poor fuel economy, engine performance, and eventually cause misfires in extreme cases. Dirty engine filters and a blockage in the PCV valve will also decrease performance and economy (a blocked fuel filter can even prevent your car from running altogether). The recommended interval for a tune up on early Z-Cars is 30,000 miles. If the car has sat for a long period of time or if you recently purchased the car, a Major Tune Up should be performed along with other maintenance (including a complete fluid change). This kit comes with all of the regular wear components needed to restore the functionality of your ignition system to like new along with other maintenance items that should be changed at the same time.

Application Notes:
The air filter is for models with Hitachi Carbs and original 73 air filter housing. In-pump fuel filter is for factory equipped electric fuel pumps.
