Why are iridium plugs better than copper?

Iridium is six times harder and more durable than copper electrode material. It resists corrosion and wear, maintaining a precise electrode gap for a strong spark. Iridium plugs typically last over twice as long as basic copper plugs.

Are R44TS plugs pre-gapped?

Yes, R44TS come pre-gapped from the factory at 0.035 inches for most applications. This eliminates the need to adjust the gap yourself during installation.

Do R44TS plugs require anti-seize lubricant?

Using anti-seize on the threads is highly recommended during installation. This prevents the threads from corroding and “welding” to the cylinder head so the plugs are easy to remove.

Can I replace platinum plugs with R44TS?

In most cases, yes. R44TS can directly replace platinum plugs. Both provide high performance and longevity. Iridium may last a bit longer, but platinum plugs are still a step up from basic copper.

Do I need new wires with R44TS plugs?

Not necessarily – if your existing wires still have good insulation with no cracks, you can reuse them. But for optimal performance with new plugs, consider upgrading to a fresh set of OEM-quality wires.

Is a tune-up required with R44TS plugs?

A full tune-up is not required but is recommended to get the most from new plugs. At minimum, check air filter, fluids, and inspect other ignition components. Replacing worn wires, caps, etc will ensure optimal spark.

What’s the difference between R44TS and R43TS plugs?

Both feature iridium electrodes, but the R44TS has a tapered ground electrode for a sharper spark focus. The R43TS has a traditional flat ground electrode.

Should I gap iridium plugs to spec myself?

No, never adjust the gap on pre-gapped iridium plugs. The thin electrodes risk bending or damage that will ruin the plug’s crucial fine tolerances.
