Anyone know the gap off hand so I don't have to read this manual

As a rule, you don't gap irridiums. They come pre-gapped. They do it because the irridium post is so fine that you would likely break it. They are also forgiving in as much as if the gap is off a little, it should make no difference. I've used them in my boat and in my truck, they're the only way to go. AND, I've never gapped them. Just check with my buddy who works for Denso and he said same thing. All of theirs go out pre gapped.

Thanks for the tip we installed the new plugs and didn't gap them and she ran great! The previous owner mixed 4 iridium and 4 regular spark plugs and 6 of them broke while trying to take out but we purchased this special tool and they were easy to take out.

put "never seize" on the plug threads. They sell it in little tubes at the counter at the auto parts store for like $2.

USE IT.


No really. I'm not kidding. You'll never break a plug again.

I have put OMC triple guard grease on the threads of spark plugs and never had one that would not come out real easy, and my boat is in salt water 6 months of the year for the last 10 seasons at least. I have found that it works better than antiseize which seems to cake up in the threads.

I used never seize on 4 and the grease lightly on four will see in six months which ones come out easier. Can't believe that broken sparkplug tool was so easy to use and I was able to remove all my broken spark plugs with no problems at all.

I have been changing plugs in my own engines, all different kinds, for over 40 years. Never broke a plug. When that happens 99% of the time someone put it in too damned tight. Or in a boat engine you might have water leaking on it
And then you have corrosion. Watch your tightening torque. Taper seat plugs, hand tight and 1/8 turn more. Gasket, new hand tight then 1/4 turn, used, 1/8 turn. Do it this way you won't break plugs.
I used to use anti-seize and a torque wrench. Here's what happens, the torque specs are given for dry threads. If you lube em with anti seize or even grease or motor oil, then what happens is that you have lowered the tightening torque need so to speak and will over-tighten em if you use the stock specs. So if you want to use any kind of lube on the threads you can't use the stock tightening specs, you need to reduce them, I'd guess by 1/3rd or so. Like from 15 to 10 ft lbs.
I did an experiment once, I use anti seize on the plugs in my 4.0 Jeep (iron head) and used factory specs. Next time I just used a bit of motor oil and the hand tight 1/4 turn more to seat the gasket. With the second method they came much easier.
Try this the next time you remove: loosen the spark plug just a tiny bit. Spray compressed air to get rid of dirt. Then I take a can of PB Blaster with the spray wand, and spray a bit in the plug seat area and LET IT SIT. Then do each one like that, go do something else for an hr. Come back, spray a bit more, let it sit. I bet they will all come out.

I did the 16 plugs in my Jeep 5.7 Hemi last Oct, some of them were really tight from the factory. Thats how I got them out without breaking a plug. When I put them in, no antiseize, just some Mobil 1 on the thread, and a hand calibrated by 40 years of changing plugs....hand tight and 1/8 more (taper seat into alu heads)...
Once I have done it my way, my plugs come out easily.....

I trust my hands also, hand tight and 1/4 more is better than any torgue wrench I know of. They were over tightened, checked for leaks and none were found. Spark plugs were not even the same kind on the right head. Trusted the dealership to do it which they said they would, after my hours of work they said they didn't charge me and it was not done. Total jackasses!!!!
