The only thing I can say is that the electrodes were well protected in the package and the gaps were perfectly preset. I paired these with new Accel coil packs and my 4.6L crown vic runs great! More power.

You need to consult Ford sites for that info. Be very careful gapping iridium plugs; the tip of the electrode is tiny and easily damaged. NGK SAYS NOT TO USE A "DISK" TYPE OF GAPPING TOOL. I agree, but if used very gently you can use one to confirm the gap. Otherwise use a "wire" gap tool or feeler gauge.

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.

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/

Ultimately if a ford part has been superceded you should check with you dealer. Installing a wrong spark can damage a engine. A quick call to the dealer will easily verify. A tip to you is autozone carries these sp500 locally for the same price.

No, it's for 2004 and upyour 2003 f150 has a different size and style spark plug. You can use a regular 5/8" spark plug socket, I believe

It was last Fall when i changed the plugs on my '01 Suburban. The new requirement for the 5.3L GM engine is a spark plug gap of .045" vs. the original requirement of .060. I would make them all the same at .040 or .045, which ever is correct. Check through Google. The plugs on my vehicle had never been changed up to 160k miles and what a difference. I think the recommendation is to change them at 100k.

sry i put these on my camry but I can explain why Iridium is better than any other metal. Metal is conductive but metal oxidize is not. The unique property of Iridium is that both the Iridium metal and the Iridium Oxidized are conductive. Even the Iridium on this spark plug is oxidized, it is still conductive and will function well.

mine are gapped at .45 thousands but I race mine and have a MSD hooked to it a few thousands volts running these in a set of pro comp alum heads. it is a standard plug for normal every day driving. they do make a colder plug but I am at 5000 feet or more so I run these. hope it helps

This plug has a higher heat range than the factory installed spark plugs.Installing this plug may decrease performance.Check your owners manual for the correct plug.

To be certain, look underneath the truck on the drivers side near the fuel tank and see if there are 6 ports with fuel lines attached on the existing one. My 1977 C20 clled for a 3 port, but looking under the truck, it had a 6 port. Put down a piece of cardboard and look. It is difficult to send back anything electrical.

I used NGK Iridium sparkplugs on my 2001 Yukon. From measuring the outside, it certainly looks deep enough to meet your needs. Hope this helps.

Thank you for inquiry. According to manufacturer, unfortunately,there is no single answer to this question. As spark plugs grow older, they lose their sharp edges as material from the center and ground electrodes is slowly eroded away. As the gap between these two points grows, the voltage required to bridge the gap increases proportionately. Even the best ignition systems will be strained to supply enough voltage to completely burn the fuel. It is at this point, when fuel is being left unburned, that the time has come to change spark plugs. Replacing worn out spark plugs with new ones (with sharp new edges) effectively restores the ignition system's efficiency. Misfires are reduced, power is restored, economy of operation is enhanced and emissions are reduced. The best guide is the manufacturer's recommendation for your vehicle, as this particular service varies from brand to brand and model to model. In the absence of this information or in conjunction with it, you can rely on the advice of a mechanic who is familiar with your type of vehicle. In the best of all worlds, this would be a mechanic who is also familiar with the vehicle you own. If you find a good mechanic, whether dealer or independent, stick with him. The better he knows your personal vehicle, the better he will be able to diagnose and service it. The end result is very much like a doctor-patient relationship and, in the long run, you will have a healthier vehicle. Don't hesitate to contact us if we may further assist you.

If you replace the distributor cap with a good quality cap with brass terminals (distributor caps with aluminum terminals are junk), get a good quality set of spark plug wires, this coil will help your jeep run better, because this is a higher out put coil than stock. You will also be able to open the spark plug gap another five thousandths of an inch, which will also help. (I increased the spark plug gap on my truck, and it seemed to help a little. You might want to try it, or not).

Yes, but may be too long for some applications. These are the longer ignition wires, depending on which ignition coils came with the truck. If the spark plug wire connects to the coil on the very bottom, as well as the ignition coil mounts to the valve cover with one bolt on each side of the coil, these will be too long and have an extra 1.25" of slack. However, if the plug wire connects to a downward-facing boot on the side of the coil, with the ignition coils mounting the valve cover with one bolt on top and one on the bottom, these wires are the correct length.

Bring up google. Type in ( Denso spark plug Iridium for 95 acura integra ) When the Website comes up, follow instructions. RP

You can check the placement for your car on this site: http://www.ngk.com/product.aspx?zpid=10221 I installed these in my Dodge Ram and did not have to gap the plugs.

there should be a red light on the insight when the truck is in regen. not sure if you can monitor the soot grams. try to google it.
