Hi,

Recently purchased a 91 hatch, it has a b16a block and a vtech head stamped pr3-3. i'd like to get some new spark plugs but the zex ones that are in it i cant find a cross referrence to. Anyone know what car i should be looking up for parts?

 

Sparkplugs for a 99 B16 SIR will work.

 

Pr3 heads were found on all generations of B16A, B16B (ctr), and B18C5 (ITR) engines.

Get plugs from any B16A Civic Si or Del Sol B16A

 

great, thanks for the help

 

well, i put some bosch 4 platinums in, referenced the del sol b16 vtec, car runs like crap. Hard starting and hesitates sometimes from a starting stop. I advanced the timing a little bit and it got better but still sputters and once backfired on takeoff, just seems to be in the first little bit of the gas pedal, after that it runs great.

 

Bosch plugs suck bigtime!! Go NGK, your engine will love you

 

ok, i bought some ngk iriduim plugs, wow, who would have thought a spark plug brand would be so different. Car fires right up and runs great, bosch plugs are definately not for hondas.

haha..i found that out to,,even those 80 cent champions are better...for some reason bosch spark plugs and o2 sensors just plain suck on hondas

 

yup bosch plugs suck in hondas...weird though my bosch single wire o2 has never given me problems
