If you have a 2000-2004 Isuzu, make sure you only use Denso K16PR-P11 spark plugs. The 2000-2004 engines have the GM/delphi "ion sensing" ignition system where the spark plugs are used as a sensor (when they are not firing) to measure the electrical resistance of the gasses in the combustion chamber. Other plugs may cause the ECU to register a code (misfire code: P1340).
Since my Rodeo is an 01 I'll assume these are the correct plugs fr my engine. I've just looked at all my local sources and these plugs are not available.. I did find them on Amazon and E-bay however..
My Q is this:
Is there a BOSCH or NGK equivalent to the DENSO plugs?
Assuming there are a number of gents using these "correct" plugs where did you get yours?
Are these DENSO plugs what everyone is using or is there another/better option?
