Description of ๐Ÿ”Œ Autolite 3924-4PK Copper Resistor Spark Plug: Affordable Pack of 4 for Enhanced Performance

Copper-glass seal bonds insulator, terminal post, and center electrode together to provide a tight seal that is 100 percent leak-proof. Cold-formed steel shell and precision rolled threads, with one-piece terminal post to add strength. Multi-rib insulator reduces danger of "flash-over". Resistor reduces radio frequency interference (RFI) and electrode erosion. Full copper core electrode provides better performance in all conditions.

Efficient and Reliable Spark Plug

This spark plug packs a punch with its reliable performance in my car. I noticed an instant improvement in the engine's idle and acceleration. The copper construction ensures efficient conductivity and longevity. The only downside is that they can be a bit pricier than other options, but it's worth it for the peace of mind knowing my automotive ignition system is in good hands. Overall, a great investment for any car owner looking for high-quality ignition parts.

Pros
  • Good conductivity due to copper material
Cons
  • Not as long-lasting as some other spark plug materials

What a new set of spark plugs does to a car

I've replaced the spark plugs and Coils in my Porsche Cayenne. The check engine light no longer lights up. The car works like a soft top. Great shade tree mechanic project.

Pros
  • A copper-to-glass gasket bonds the insulator, terminal block and center electrode together, creating an airtight seal that ensures a 100 percent leakproof seal
Cons
  • I'll keep quiet

Fake? in spark plugs and wire

Purchased and installed. They looked brand new but the Autolite on the sides was really light grey. I keep all my butts and for 10 years they have had dark clear letters on them. The logo was installed in my car and it was always missing. I checked that the engine does not have two cylinders. Checked the spark plugs, good spark. I checked my msd box. No codes. I removed all the spark plugs and put the old ones in. And guess which car starts and runs as usual. Attention buyers

Pros
  • Resistor reduces radio frequency interference (RFI) and electrode erosion
Cons
  • Doubt
