rider Posted November 29, 2017 Share Posted November 29, 2017 Its time to change out the iridium plugs next year (NGK BKR7EIX) and I'm wondering whether it'd be worthwhile doing the breather pipes, coil packs and clips at the same time seeing they are all original 22 year old components? With coil packs and clips are they best left alone till they fail or is it worth spending say £200 on NGK alternatives or £400 on OE Denso replacements (from USA, they are £650 in the UK)? Also with the clips is it best to just replace the housing or go for the pigtail option and solder onto the loom wiring? Quote Link to comment Share on other sites More sharing options...
Scooter Posted November 29, 2017 Share Posted November 29, 2017 Hoses you'll almost certainly need as they tend to split. I'd personally leave the coil packs, under the if it ain't broke don't fix it category, I have the pigtails from someone on here who was getting rid of a load they had, but no direct experience of replacing the clips either way. I recently did the plugs on one of mine and the clips were in very good order. Going to do the plugs on the other soon and might not be so lucky there!

peter richards Posted November 30, 2017 Share Posted November 30, 2017 I changed mine when the clips were broke , in the end I changed the lot plugs coil packs and the problem clips , then wired one clip the wrong way round lol easy to do as the clips fell apart so didn't disassemble . ,at least my original coil packs are here just incase, as said id leave them alone Quote Link to comment Share on other sites More sharing options...
rider Posted November 30, 2017 Author Share Posted November 30, 2017 Appreciate the input gents. I'll leave the coils as is and just get the plugs and hoses and buy in a set of pigtail clips in case any give up when disconnected from the coils. The plugs haven't been visited in almost 10 years so things may have got themselves brittle in that time. Quote Link to comment Share on other sites More sharing options...
bignum Posted November 30, 2017 Share Posted November 30, 2017 Inspect the coilpacks around the mounting lugs and also where it connects to the spark plug, if any are cracked its time to replace as thats when misfire problems start, last thing you want is being 500 miles away and get a misfire.

Swampy442 Posted November 30, 2017 Share Posted November 30, 2017 Im of the opposing view, if you can afford to change the packs then do it. New plugs, clips, hoses and coils mean 10s of thousands of trouble free miles Quote Link to comment Share on other sites More sharing options...
