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: http://cgi.ebay.fr/ws/eBayISAPI.dll?...=STRK:MEWNX:IT 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. Last edited by alundra; 28-03-2010 at 20:53.

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

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
