Problems With Spark Plugs

[ken12292703]

Dear brothers and sisters, please give a little help by giving ANY comments on my plugs.

Engine: BPT 180
Maximum Boost: 0.7 BAR
Fuel Pressure: 35 PSI
Fuel Pump: Assume standard as i don't know
Injectors: Assume standard as i don't know
Consumptions: No Boost ~ 26 litres @ RM50 @ RM1.92 per litre = 180km
50% Boost ~ 26 litres @ RM 50 @ RM1.92 per litre = 120km

Exhaust: Straight Flow 2 1/2 inches with a straight muffler
All others are standard

Here are the plugs i captured today~ DENSO IRIDIUM IK24

In the morning, cleaned it up and install it again. Not as clean as new but still left some brownish.

This is what happened after some drive WITHOUT BOOST~

I wanted to get a set of new plugs now, i am wondering to stick at DENSO IRIDIUM IK24 or go for DENSO IRIDIUM IK27 as i am considering future modifications as well. DENSO IRIDIUMS are not cheap~ :confused_smile:

Thank you!!!

Yeah, i feel that my plugs are a little oil fouled at the low rpm side because of the cold IK24 heat range 8. The thing i am not sure is when i Wide Open Throttle; don;t know running rich or lean. :confused_smile:
