NGK Spark plug

I've recommended many times to toss plugs and replace with NGK (you can read about my experience in prior post). You have hopefully educated newbs to follow you.

Pros: replace with NGK

Denso Spark plug

I'd opt for a set of 1 step colder plugs. Ideally non projected tip like [Denso 5749](https://www.fcpeuro.com/products/vw-spark-plug-denso-5749) or [NGK 4905](https://www.fcpeuro.com/products/vw-spark-plug-ngk-r74388). Though these are costly.

Pros: non projected tip
Cons: can be costly
Mileage: 15000 km
Part number: 5749

Denso Spark plug

They look good but if the vehicle has 83k, they were replaced before, Denso is OE on toyota and Autolite are shit plugs so no way they were in since the car was brand new.

Pros: look good
Cons: shit plugs
Vehicle: Toyota
Mileage: 133575 km

Yep. Ordered some NGK iridium plugs on Amazon, 2600 miles later the car was misfiring. The gap was toast. Counterfeit for sure.

Cons: misfiring, gap toast
