Bosch Tune-up Kits
Includes distributor cap, rotor and spark plugs.

*NOTE: Two distributor shaft sizes were used on 1985 240 non turbo models. you’ll have to measure the shaft OD or the rotor ID to ensure you get the correct rotor.
If you measure 3/8” / .400” use tune up kit number IK114(X) (rotor #04170). For 9/16” / .565 use kit number IK116(X) (rotor # 04138).
**Rex-Regina cars will require a different coil wire (#6842734).

A properly tuned ignition system is one of the most important factors of any engine. It will keep your engine running smoothly, economically and will deliver the most power. The increased heat under the hood may lead to premature degradation of the ignition wires. These wires are made by the original equipment supplier to Volvo so you are assured of the best quality in replacement wires.

Ignition wire is included with our kits.

If you have a 1976-1995 4-cylinder Volvo with marginal or damaged spark plug hole threads, you can now make a quick, professional repair in minutes without removing the cylinder head. Kit includes everything needed to permanently repair 2 spark plug holes. Works on all B21, B23 and B230 engines. Remember that you can reduce the chances of this happening by using a small amount of anti-seize compound on the spark plug threads every time the plugs are replaced. Kit contains 1 specialized reamer tap, 2 thread inserts and locking compound.

The first suspect in a poor-performing engine always seems to be the plugs.

On overhead cam engines one should expect about 30k miles but, as these are getting older, they are wearing out sooner too. Contaminants such as oil and incorrect fuel mix will shorten the life of a plug dramatically.

We have been using and selling NGK spark plugs since the seventies because they’re the leaders in copper core technology. Copper is a great conductor of electricity and heat, so copper spark plugs perform well under all extremes and have a large conductor tip for maximum spark area.
