Spark plug Autolite or AC DELCO

AC DELCO Spark plug

AC Delco/NGK.

IMHO, this is one of the times where the OEM stuff might be the best way to go, especially if your engine is otherwise stock. It's really common to see these trucks get well over 150,000 out of the original plugs and wires. They're kind of expensive but they just last so long it's worth it.

Pros: long lasting, OEM quality
Cons: kind of expensive
Mileage: 150000 km

Pros: working fine
Cons: gap was incorrect

I have a 2019 GTI with 65k km. I decided to do plugs and when I saw how expensive OEM were, I said screw that, i'm going to try the iridium auto value basic ones. I thought the difference in quality would be negligible. I ran the Autolite XP5325 plugs without gapping. All seemed fine but then when pulling on to highway under load at 3k + RPM, misfiring like crazy.

Cons: misfiring under load
Vehicle: Volkswagen
Mileage: 65000 km
Part number: XP5325

I bought Autolite spark plugs but after researching I should of bought NGK. Right after replacing them when I accelerate my car jerks or misfires when driving. When at an idle I felt my car jerking.

Cons: car jerks or misfires
