Spark plug question
My 05 TL just crossed 200k, so time to change those plugs. At what point do the coil packs get changed? Coil packs have never been changed to my knowledge. |
When you get misfires

Thanks!

FWIW, the spark plugs are due at 210,000 miles; leave the coils alone unless one fails, then replace just that one.
|
Yeah, the coils aren't really a wear item. They either work or they don't. And if you get one that fails, purchase one used, like on eBay. They're all over the place since the J engine is common, and they don't go bad often. Used is way cheaper than new and just as good.

Both times that I've pulled my NGK plugs after 105K miles on them, they still had the original gap. These plugs are probably good for 200K+ miles....but spending ~$50 dollars every ~7 years/105K miles is a no brainer....

This one’s been neglected. I’d bet the plugs haven’t been changed either. Just did a junkyard run last week. The trunk lid was rusting, and the nav was out. Picked up both for $125. So I’m ready to throw a few TLC bucks into her. Already took care of that nasty rattle which was the timing belt tensioner. So new belt, tensioner, pulley and water pump. The engine is a little loud, so I think the lifters will need attention too. On deck, plugs, tranny fluid dump, and internal led makeover. |
(CURIOUS) " The trunk lid was rusting," Where specifically was the deck lid rusting? Have not seen this issue on 3G TL models in my area!
|
If you’re looking at the rear of the car, driver’s side bottom to middle of the lid at the crimp. I’ve never seen this as well and I live in Minnesota with plently of salt and snow. I’m guessing there was some “repair” work done there at some point. |
On the NGK website there a few choices for the 2007 3.5L engine in the TLs..just wondering which model members here have had good results with?

IZFR6K11
These iridium plugs last an incredible long time as I've seen 150,000 miles and no problems. |

ok thanks, I will grab the IZFR6ZK11

You'll be surprised how many people go in for a simple $60 spark plug change and come out with all crappy aftermarket coils and who knows what spark plugs with a whopping $2-500 bill. Some mechanics....

replaced mine with the OE NGK ones and WOW what a difference they made. car only has 100K on it.

I've never noticed a difference with new plugs. Which is sort of disappointing considering they're not a real cheap maintenance item. I think it's because the NGK Iridiums last for-freakin-ever.

What was in there before? The OEM plugs? If yes, I'm having a hard time believing they made any difference at all. I changed out the factory OEM plugs on my J30 equipped Honda Accord at 140,000 miles and they made virtually zero difference in performance, the smoothness of the engine, or the fuel economy.
