Use the stock NGK plugs to get the best performance out of your engine.

 

Spits are junk. But they certainly won't "crack your block".

Just use the proper NGK platinums...... And they are expensive but you only have to replace them every 60,000 so .......

i got the NGK platinums at my local nissan dealer for $11/ea. the cheapest i found them for was $9 on www.courtesyparts.com. i opted to just get them locally since the shipping would have basically evened out the price.

I purchase my plat-plugs for $9.99 at salvo auto parts store, but i don't know if they have location outside of Maryland.
