Spark Plug Caps

Spark Plug Caps
Most caps that we stock are new, as the old stock is becoming increasingly hard to obtain. NGK have by far, the largest range of plug caps and most are resisted.
The non resisted caps have part numbers such as LZFH & R90 which are right angled with different fittings for SAE (this is known as a bullet fitting on top of the spark plug).
Please note that some spark plugs have a removable top, some have the M4 threaded post and some have the SAE bullet fitting. If purchasing a fixed bullet fitting, a cap which takes the bullet fitting will also need to be purchased.
Some old looking caps that we sell include:
HTC (Straight)
WCX600 (Right Angle)
and R90 (a replica of the Lodge plug caps.)

The Green Spark Plug Company is a family run business with over 40 years of experience. We have sold over one million spark plugs and also stock a huge number of related products for modern and vintage engines.
