Iridium or Platinum Spark Plugs VS OEM?

Platinum plugs ako. Mas matibay and better start up time.

Just use what is recommended. Iridium is required on my turbo engines.

Agree.

I would get the Denso brand whether it's copper, platinum or iridium.

When I still had my previous Avanza, Denso copper plugs ang gamit ko for almost a decade. I usually prefer to change plugs every 5,000 kms since mura lang naman ang Denso copper plugs.

In my case, I'd stick w/ iridium since that's the stock plugs our n/a car came with.

W/c leads me to the question, isn't iridium the oem spark plugs of vehicles nowadays?

do what you gotta do so you can do what you wanna do

Not all cars. Entry level models use regular spark plugs.

Denso Iridium Long Life (OEM) spark plug is rated for 100k km. kaya lang, hindi nagpapasok ng Denso Iridium Long Life ang local distributor.

NGK G-Power Platinum spark plug is rated for 48k km. NGK G-Power Platinum is available in most auto supply shops so ito gamit ko.

NGK Platinum IX spark plug is rated for 65k to 80k km.
NGK Laser Platinum spark plug is rated for 120k to 160k km.

May idea po kayo kung magkano ang genuine denso iridium at NGK Platinum spark plug?
