Iridium Spark Plugs
Iridium Spark Plugs are engineered to offer excellent engine idling stability and a smooth performance.
- Iridium offers excellent engine idle stability and smooth performance
- One-piece suppressor seal blocks radio frequencies that can affect vehicle electronics
- Suppressor seal meters spark energy for long electrode life and seal against combustion leakage
Platinum Spark Plugs
Platinum spark plugs are designed to deliver long-lasting performance and maximize durability.
- One-piece, fired-in suppressor seal blends three glass types for a gas-tight seal
- Helps reduce radio frequency and engine interference, regulate spark plug energy and seal against compression pressures for long life
- Double platinum point pad on center and ground electrode offers durability and consistent voltage demands to help reduce wear on ignition system
- Pure copper core results in cooler electrode temperature for durability and superior fouling resistance
RAPIDFIRE Spark Plugs
RAPIDFIRE spark plugs are made with ribless insulators to help optimize plug-to-boot seal.
- Solid-state suppressor with two-piece glass and brass seal
- Helps reduce radio frequency interference, regulate spark energy for long electrode life and protect against high combustion pressures
- Pure copper core provides great heat transfer and helps maximize plug durability
- Platinum on center electrode enables superior spark characteristics and helps reduce voltage requirements of the ignition system
- Ribless insulator provides a great plug to boot seal
Conventional Spark Plugs
Designed with a high-quality copper core, these spark plugs help deliver reliable performance.
- Black onyx coating helps prevent corrosion
- Copper core provides great heat transfer and helps maximize plug durability
- Ribbed suppressor seal extends resistance and helps prevent spark “flash over” and misfires
- Nickel-chrome alloy sheathing helps prevent corrosion on center electrode
- Available for use in marine applications

The old truck hasn't started this well in years

Fit perfect. Made startup on my 6.5L a breeze. I can't speak for longevity, but so far so perfect.

bought 8 of these.....dropped one, my luck, could not find. Ordered this one to finish out replacing all glow plugs. They work great. Fixed my hard starting issues.

Well packaged, high-quality glow plugs. These are supposed to swell a lot less vs older models.I'd recommend using a torque wrench to *remove* the old ones... any force over 35-40 ft-lb is likely going to break them creating a pretty huge issue to solve.

If you need Glow Plugs, these are the ones to get. They are self-limiting so that they won't continue applying power after they reach temperature. This will help prevent swollen glow plugs that are next to impossible to remove..

Originally i thought i would have to install a manual controller for these because they have a longer warm up time, after a little bit of research i found i did not have to do so. Installed in a couple of hours and now the truck starts right up when cold again! These are also self regulating so they will not burn out, i definitely recommend them over the stock 9g and 11g

Very well made and all.I purchased for the oddball application of assembling a smoke machine leak tester.But the outcome was that diesel glow plugs are not a great match for this use.The glow plug required too much current and produced too much heat once it "turned on". Chose to use resistant wire on wick instead, which worked out to much more moderate current and controllable heat level.FWIW. As a glow plug this is probably just fine for those vehicles that it fits.

The product is as advertised ... and 50% cheaper than that sold at the Chevy dealer (for the identical product). My 2001 diesel van now starts in cold weather again. Make sure to check the function of the glow plug control module as well. The control modules tend to fail after a number of years as well, and if malfunctioning, will fail to properly sense the glow plugs. My module voltage checks were normal, so I only had to replace the glow plugs.
