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.)
