Watch the videos below to get a "feel" for what this kit can do. The M103 is notorious for fouling spark plugs - mainly due to oil getting by the hardened valve stem seals. This was a problem when these engines were new and only had 60,000 to 80,000 miles on them. Replacing the valve stem seals is the permanent solution, and as long as the engine has good compression, it will usually stop the oil burn.
Product Details
But what if you don't want to take the time or expense of replacing the valve stem seals? You want to prevent the rapid fouling of the plugs so you can drive the car and not lose power. Installing the anti-foulers is not a permanent fix, but it might get you to buy while you look for repair options or vehicle replacement.
These are solid steel high-quality machined parts with the right beveled edges for the M103 engine. 6 are included along with 6 NGK - V groove spark plugs ( these are the best anti-fouling plugs for these engines.
IMPORTANT NOTICE: We have found the very thin anti-corrosion plating flakes off over time with heat. It will not cause any damage. It is cosmetic, and unless you park the car with the hood open in the rain, corrosion is not an issue with these in the head. If you are concerned, you can use a propane torch and wire brush and burn it off before installing. When you remove them, blow down in the spark plug hole with compressed air first.
