Default wat are the differences in spark plugs

as far as the NGK bkr's and the zfr's? both are the v-power plugs and when i compare them they look the same but one is just a lil smaller than the other.

wats the deal with them. ppl tell me to get the bkr's and i have but i dont see the reason. ran both types of plugs and it hasnt solved my problem.

sgT I have a ?
I pulled zfr7f-11 projected out off my B20 vtec and went to a performance shop near my house to buy replacements and the guy asked if I had an H22 and I said no why? He told me the zfr projected where for the H22 and asked what motor I had and I told him a B16 (I don't want the theves that hang out there to know the truth) and he said I should never run that plug in a B16 because of the length.He said It could hit the piston? He said I should run the bkr7e-11.
The zfr7f-11 where put in buy the place that dyno tuned the car. Which I and know thrust.
which should I run?

Going by the design symbols on the NGK website, the difference between the two plugs are the extended gap (not sure which gap this is, may be from electrode to body). The reach is the same as is the size and threads..even the gap is the same (11 or 1.1mm).

It really shouldnt matter too much between those two plugs.

I would have to look at the ZFR to say for sure what the major difference would
be, however judging by the part code, the only difference would be the reach on
the electrode. Most people use BKR7E because they are cheap and they work.
If you arent having problems with the ZFRs then keep using em. If it aint broke......
