July 12, 200818 yr comment_260319 I've found a set of these in one of my boxes - are these for a 4K? Or 4AGE? Did a quick look around the web and it looks like it's for a 4A, but from memory my 4AGE took iridium plugs (or something to that effect)? Report
July 12, 200818 yr comment_260339 4K/4K-C Plugs NGK - BP5EY AC Delco - 43XLS Denso - W16EXU-1 4AGE Plugs From 1986-88 NGK - BCPRE5-11 (1.1mm Gap) AC Delco - FR2LS 4AGE Plugs From 1989 onwards NGK - BKR6EP-8 (0.8mm Gap) I could probably cross-reference these over at work to Bosch plugs, but NGK, AC Delco and Denso plugs outweigh the effort of even wanting to do that as Bosch plugs arent all that great. *Added this to the Knowledge Base/FAQ as well.

July 13, 200818 yr comment_260460 Those plugs are set from the factory so no need to include the gap :( The number at the end of the part number, being either 8 or 11 in this instance, indicates the plug gap. :( Report
July 13, 200818 yr comment_260467 And while talking about K engine spark plugs..... If you have a 5K dished piston engine, you may use the longer electrode spark plugs from an EA falcon. Part No. BRE527Y-11 They have a 1.1mm gap so you will have to reduce the gap to .8mm for a K engine. MAKE SURE YOU HAVE A DISHED PISTON 5K FIRST!!!!! Putting these spark plugs in a normal flat piston engine will damage something for sure. Edited July 13, 200818 yr by Xany Report
July 14, 200818 yr comment_260679 Those plugs are set from the factory so no need to include the gap :D Like hell they are!!!! :( Yeah I know they're supposed to be, but never are, so an extra 2 minutes will a feeler guage is always a good idea! :( Report
July 14, 200818 yr Author comment_260683 Cool, so they're 4K plugs. Next question: Does anyone want them? Free to a good home. Report
July 14, 200818 yr comment_260707 Iridium and platinum plugs can be damaged by gapping them, they've only got a really thin coat of noble metal, and if you chip it they'll corrode. Like hell they are!!!! :( Yeah I know they're supposed to be, but never are, so an extra 2 minutes will a feeler guage is always a good idea! :( Report
