Yeh, I saw a YouTube video from Vivid Visual saying he managed to replace the plugs without removing the manifold cover but they didn't show any of the steps, so who knows. For the life of me, I couldn't get my tools into the tight spaces and believe me I have a ton of tools and adaptors.
Look at the Spark plug thread. It is pretty easy to get the plugs out without removing the manifold. Yes it is a bit of a fiddle. It took me about 2 hrs outside on a hot day being deliberate taking my time and one beer break. A combination of extensions and swivels in quarter and three eights is the ticket. Cheers
@PatriotOne the trick is to pull the rubber boot from the coil, it will separate and you can then remove the plug. Second tip, use 2 (TWO) swivels to get at plug three. third tip... DO no use a magnetic socket or one with a rubber inter grommet. IT will stiick to the plug and keep you from pulling out your conglomeration of extensions and swivels. Just use a regular socket and after tightening it will pull right out of the cylinder.
I disagree with tip #3. I think by doing this you open yourself up to possibly damaging the new plug if it slips a bit in the socket during the fiddly re entree. Not that you care, I do give you two up for your trick and tip #2. Cheers.
That’s not entirely accurate given the number of Denso failures with ceramic cracking or premature blowouts that have been reported on these forums alone.
Sorry but just the examples you gave seems like a lot of human error especially the blowout one(s), plugs installed with that much thread does not just blow out if tightened correctly. When it comes to the maker of plugs I tried Hks and got slight shake at idle which is cool if it was a older car with a cam but the denso’s at 24 worked great for me kicking @$$ and going to fast to take names
up for your trick and tip #2. Cheers.
