What spark plugs do u guyz prefer for a b series vtec motor. WHat do u guyz use and how good are they? im currently about to perform a full tune up and i'am wondering on what would be more beneficial for me? i have bosch step 2 plugs, but some have mentioned to go for NGK platniums (irridium or ressistor)instead, just wonder on what you guys are running and what is preffered in B series engines

TIA

 

Iridium will add the most power. I have them in my B16a and I love them.

I'm using NGK R V power and I like it...

these are good, and anything but autolights
and make sure they are non-platinum

 

ya we ended up using NGK V power plugs on my friends b16, though i still prefer my bosch 2's

 

NGK BRK6E-N11. You can find these at Napa Advance Auto Parts or Monarch.com(?). They had it in stock at the Napa Main Store or other places can order it for you. I think it was a little over $2 a piece.

 

Cold plugs...especially good for n2o...and perform very well.

 

ive hat NGK iridium IX's and now i have Denso iridiums... htey aer both excelent!!!
