do you gap these iridium plugs the same way as you do with standard type plugs ?

That was the recommendation I found on the internet. Gap mine @ .54 and have a 2002 f-150 with a 5.4 liter engine.

No. Should be pre-set. However, you really should check gap on all plugs you install into an engine. It is good practice, and you can note it as a reference for performance. You may wish to vary the gap based on your requirements for performance, power of engine, and the load you place on it. If you don't know, or have a stock engine, just make sure all the gaps are the same. Use the factory recommend gap, which as we said, should be pre-set. Don't reset it unless you happen to hit the head when installing, requiring a re-check.

Most plugs are pre-gapped. These stated they were. But anything can happen during shipment. A spark plug gap tool is only a couple dollars. I always check the gap, regardless if there pre-gapped.

You have to find the part number for the spark plug you are currently using and then cross reference. NGK makes Iridium spark plugs for many but not all applications. I have similar NGKs Iridiums in my BMW, Honda Odyssey, Craftsman snow blower, Honda mower, and Honda power washer. I wanted to put these NGK Iridiums into my Craftsman mowers and Craftsman leaf blower, but NGK does not make it for those applications. If you are already using an NGK plug, there is a good chance NGK makes the Iridium version. Bottom line, check and cross-reference.

Yes; The composite (red, white, and yellow) plugs are shared with the component plugs.

Spark plugs, their gaps, and coil packs, have nothing to do with each other, other than being used in conjunction. It is like asking, "How much water pressure do I need to wash my car?" For the proper size and type plug, gap, and coil pack (none of which may even be used on your car!), you may find the info for free in your owner's manual (spark plug and gap info only) or at your local dealer or auto parts supply store, both online and brick-and-mortar. Good luck!

Spark plugs are appproximately gapped from the plug manufacturer. You should consult the user manual from the ENGINE MANUFACTURER for the correct gap.

No they do not need to be gapped. The spark plugs come with a tube cover protecting the threads and electrode incase the box is dropped.

the r44ts is a copper resistor plug, the 41-993 is a iridium tipped plug that is already pre-gapped for a high energy ignition, what is the year and make of your vehicle? i do not believe these two are compatible based on this information, plus i believe the r44ts is a thicker diameter plug.

No, and not all have that gap. It is merely a matter of the rod sticking out a bit further from some housings than from others. If you saw a schematic of the parts, it would make more sense. Think of it as a guillotine (that's what it is, by the way, a guillotine gate valve). All it takes is a bit of design variance in the height of the housing, length of the rod, or height of the gate to cause this. The actual 'seal' occurs because of two rubber o-rings inside each gate-block face. In fact, the valve is actually closed BEFORE you have pushed it completely to the closed-position, anyway.

Hi. I am not sure, however, I used some forums by typing my car into it then used a search engine asking the question as you do? I notice a better performance since replacing them. My mechanic liked not having to gap the plugs. Even better I saved Labor cost as a result. I recommend them. I hope this helps. /Satisfied Al W/

Hello, No, we do not gap them. The mechanic installing the plugs should verify the gap upon installation. Thanks, Jen

You should not need an adapter for the harness if the bulbs themselves are the same number

No different vehicles have different type of gap electrode requirements. so check with the dealer

It will be a gap. they are visually rectangular but due to manufacturing processes (hi temp) sides got a little curve and looks like hand made. Just allow some space between them.

The connection seems to be the same the same size as the incandescent. Length wise because they are flat they are shorter which is not a problem.

For that you need to check the specs of your vehicle and the spark plug size. All I know is that if your car original spark plugs are Iridium then you should put Iridium. Otherwise your car may not start at all. But if your car original spark plugs are standard then you can upgrade to Iridium and have no problems.
