NipponDenso Platinum TT gap?

[Nick R]

My car specs .060" as the gap, but these come as .040

My question is, do these need to be gapped to .060, or am I supposed to leave them as-is?

EDIT: And I just noticed the heat range on them is 16. The HR on the V-Powers, G-powers etc are all 5. Would this make them trouble?

Get the correct part number plug that is correctly pre-gapped and heat range for your vehicle.

You have the wrong spark plugs

The plug manufacturer rules. It sounds like an improper heat range, why?

Just gap it to 0.060 and you will be fine.
Denso 16 and NGK 5 is pretty similar heat range

Again, plug manufacturer rules.

Different plug mfrs. use different numbering systems.
Spark plugs that have extended tips have a wide range of operating temps that will still keep the plug clean, with no fouling or overheating.

The reality is that plug substitution by other brands rarely causes problems because of heat range.

Normally, getting factory plugs is best, but you chose a very high quality modern replacement.

By all means, gap the plugs where they should be! Use care. Get glasses if you need them! It IS odd that a plug specd for you car would be off by so much. Make sure they are the correct substitutions -do this first.

I haven't boought em yet. The reason I ask is because they are on sale at the local Advance ($1.99 normaly $3.99) so I was going to pick them up for future use. My current NGK V-Power Coppers only have 5,000 on them so I'm not going to replace them for a bit yet.

I have noticed on some Iridium plugs for the gap to be tighter out of box. It may be to compensate for finer spark so the kernel doesn't get blown out in higher rpms. This is the first time I have seen these plugs from you link. Honestly I am skeptical of fancy plugs, and additives.

From experience my favorite plugs for stock application are NGK V-power copper.

Do not gap platinum and iridium plugs. Gapping is for copper plugs only. If the gap on platinum is not correct out of the box, you have the wrong plugs. I haven't gapped a set of plugs in 10 years. If they aren't correct out of the box, it's a problem at the factory.

I was under the impression that it was only iridium plugs you weren't supposed to gap, because the electrode is so thin you could very easily break it. This is one of the plugs that comes up for my engine, and it will fit. I ask about gapping because of it's unique twin-tip design. I wasn't sure if it needed gapped or not.

All plugs need to be gapped to operate optimally, it is just how you gap it. Make sure you don't expose the small tip to high pressure because it will break, you need to gap it by work with the side electrode using plier to bend it.

I have not had to re-gap a plug for 20 + years IF I purchased the OEM plug. I check each plug gap and always have been within tolerance using a good wire gage.

Acura Tech is full of nonsense.
One of the worst posts ever made at BITOG.
It's too bad a a post like this is able to be viewed, becaue some newcomer may listen to him.
