myvi g3 going to replace ori plugs at 100k odo soon.
any good recommend to use, other than ori denso that cost above rm250 from sc

iridium

Haiya SC uses iridium right? Then can lasts another 100k or 5 years

No such thing as powerful, only long lasting iridium can last 100k, so don't need to pay 5x labour fee to change traditional spark plug.

parking because i think my car will need soon

but as long as use legit spark plugs should be ok kan

or will laser iridium actually make a difference?

no kick in

i research copper plugs very power cuma low lifepspan.
maybe buy tools sendiri tukar every 20k odo

wanna buy super4 bosch

No more release Bosch Super 4 except Shopee Motorsport, you know I know why... Asked Bosch Malaysia through email many years back, already discontinued.
Btw, Super 4 is not 4 sparks flame ya, the spark goes to nearest tip after worn out, thus long lasting spark plug type.

rules is never downgrade spark plug.

you want better plugs? denso iridium tt or ngk ruthenium HX.
fine tip spark plugs on both ends. standards plugs for iridium are fine tip on the centre only.

Got aftermarket racing plug example - Brisk Silver, HKS
But disadvantage - Shorter lifespan (usually around 30,000 km (18,000 miles) or 50 hours of racing) and need to upgrade the ignition coil to enjoy higher power.

If buy online, better with shopee mall, cz too many fake plug on market. I saw one post for x70, he use fake plug, end up valve parted and need to spend few k for repairs

If google, the expansive plug give better spark, more power, better efficiency hence better fc. But maybe 0.5L fuel saving per 500km drive.

But nowadays car mostly already put recommendations expansive plug and only need to change every 100k km, like Honda Malaysia model

Ngk shopee mall laser iridium or ix iridium around rm200 for myvi. Laser for save fuel and longer 80k interval, ix for performances and 60k interval. Compare to copper plug easier start, slightly fuel save and slightly hp+, better self cleaning ability because can tahan extreme heat. Copper plug after15k performance drop. Fake iridium the jarum will burned disappear then your car will misfire vibrate and even stalling. Ngk mall also sell platinum plug sit between copper and iridium range.
Try buy from Ngk or denso official shopee mall, denso more expensive > rm300. Other 'price too good to be true' seller better don't trust.
Diy change myvi easy with a 16 mm magnetic wrench, use hand tight then wrench tight 1/2 ~ 2/3 turn.

denso iridium power for most power. or denso iridium TT for slightly less power but 5x lifespan. ngk iridium is less powerful on myvi engine
