hi again all, hope u r all well.
just need a little advice on my spark plugs....they were changed about 6 months ago,at my cars annual service, and although i dont need to replace them yet (they are ngk double plats'), i want to put the motorcraft original plugs in, which i have already.
i gave the plug-areas a quick blast with compressed air to remove any gunk around them, but cannot remove the plugs. i dont want to force them for obvious reasons...i have been advised to put a little wd40 on them and leave them for a couple of hours..i will be leaving them over-night...is this ok?
any help or advice would be much appreciated.
