Denso Spark plugs.

[92saturnsl2]

Does anyone know how to interpret the part number for Denso spark plugs? I picked up a set for the truck that I just sold and I'm wondering if I can use them on my current vehicle.

The spark plugs are the new Platinum TT plugs with #PK16TT written on the insulator. The box has PK16TT 4503 written on one end.

My current vehicle ('00 Kia Sportage) requires PK20TT 4504 plugs. Is this just a different heat range? The listed specs are all the same (5/8, same thread pitch, gap, etc). Is it safe to use these plugs?

The 16 is one step colder.Safe?yes. They should work fine.

It might not be the same thread pattern or length.
