Does anyone use NGK spark plugs in their car.I"m in process of doing tune -up on 1948 ford 2dr sedan,with stock 239, and wondering which heat range to use,and if gap remains the same.

I use NGK B6L in all of my Fords ('39 and '51). If you need a hotter plug, use NGK B4L. Autolite 216's are also a good plug. I had used Champion H-10's for many years but their quality went way down so I stopped using them. Fouling problems were the main problem with them.

I use Champion RJ14YC plugs in my '47, and used them for the 25 years I have owned the car. They have the long snout that aids in keeping them free of deposits. I set them at .028. I know that Champions got a bad rep, but I haven't had any problems. Plug fouling is usually a sign of over rich fuel mixture, worn piston rings or valve guides. A compression test wet and dry, will help determine engine condition, as will close examination of the plug deposits. The H-10 plugs did foul easier, and have been replaced for years by the RJ's.
