63 AMG | One step colder plugs

$170.00

Availability: 3 in stock

NGK One Step Colder Spark Plugs

One Step colder plugs are designed to dissipate heat more efficiently, which will bring down combustion chamber pressures and prevent pre-detonation.

These plugs are highly recommended for modified engines or engines under going extra modification soon.

These plugs are not recommended for stock or close to stock power vehicles because the cylinder temps do not get hot enough, which can cause carbon buildup on the plugs.
