BCPR7E VG alternative to BCPR7ES
 

I need your advice.
I'm modded with stock T2 at 0.8 bars, intercooled, exhaust, air filter...
I'm looking for 8 spark plugs because of my cylinder head.
I saw this on ebay:

Same as BCPR7ES but the electrode is in V shape for better emssions and fuel "economy".
They're are made by NGK.

Are they a cheap alternative?

Cheers.

P.S: I ran on BCPR7ES 3 years now and i need to change them.

the V grooved are normally a bit more expensive in UK. Ive used them in road car for many 1000s of miles, never hada problem, possibly a bit better life than std type :)

Thanks for fast reply! V shaped shipped cost less less than bcpr7es here.

you have a twin spark motor ?

me? not currently, but have had two previously.
i used i heat range different on the exh side plugs as per nissans advice (6s & 7s) as opposed to 5s & 6s iirc)
secondary plugs are only there to burn off any unburnt fuels left from combustion process, was a cheap method of cleaning up exh emissions, before closed loop ECUs were the norm.
disconnecting the 2nd coil has no effect on the dyno graphs
