What is the gap on Bosch spark plug for?

Bosch spark plugs traditionally leave the factory pre-gapped for their most popular application. However, a plug may fit hundreds of engines, from cars to golf carts. Gapping the plugs to your engine’s specifications is important to prevent pre-ignition, detonation, fouling and poor fuel economy.

What happens if spark plug gap too big?

Excessive spark plug gap results when the voltage has too far to travel. Excessive plug gap also results in cylinder misfiring, a possible no-start condition, wet, black or fouled plugs, engine hesitation and rough idle. Excessive spark plug gap also happens as result of normal electrode wear and age.

Can I use double platinum spark plugs?

How do you tighten a Bosch spark plug?

Bosch recommends when installing spark plugs to use a torque wrench and the correct torque in ft.-lbs. If a torque wrench is not available, hand tighten the plug until it is seated in the cylinder head. Spark plugs with gaskets should be tightened an additional 90° while spark plugs with tapered seats should only be tightened an additional 15°.
