4AGE-20V Spark Plug

[cuscostrutbrace]

sincere,
thats a nice plug.meaning ur afr is good..or maybe lean a little bit hehehheh.

higher heat range will make ur engine coolder.its good right??? yes if ur engine is running high deg of timing or maybe a turbo or maybe rev none stop 5-8k...

problem will occur during low,relax condition..will make ur engine coolder.NA engine need around 80-90c of water temp to burn the fuel properly.and remember ecu ign timing n fuel also diff according to temp sensor.
Thats why explain the suck low end issue from CorollaGT??

Sifoo ..isnt the thermostat suppose to keep the water temperature around 80-90 deg.Even if slow driving,the temp never goes down right.But if we talk about combustion temp,thats another story,hehe

thats mean not enough fuel. not the plug too hot.
i try on my iriway 7, go get brown color, the AFR have to keep around 12.5~13.5. so your AFR should be around 14 above.

I have exp it. Denso Iridium IK-22 make 4AGE 20V low end power suck and bad FC. Should go for IK-20.

TQ

depend on your engine condition and mod. and depend on your driving style also.
for stock standard, or doesn't rev much, IK20 is good enough.
