Learn me about NGK sparkplugs...
 

Why do some NGK sparkplugs (for smaller motors) cost twice as much. I run NGK plugs in everything I own (cars, boat, m/c, small motors) ...have for decades. Why is it that most of my small engine stuff uses BPM8Y which cost about $22 for a box of ten, yet my Stihl chainsaws use BPMR7A which run $45 per box...I think the R designates "Resistor"...what's the difference, and why twice as much?

I've noticed a lot of variation in markup on plugs.
Play around with your search terms on google and amazon and you should be able to better.
I see the BPMR7A at some autoplicity place for $1.39. (edit: ok, their shipping prices blow)

Too late :(...I purchased two boxes of each from NAPA earlier. I was already at the counter so I just said "go ahead"...in hindsight, I should have just purchased the two I needed for today and looked online...live and learn :)

NOW you tell me...it's just gettin' worse :p

OK, the plugs I purchased are going back :). Checked out a NGK wholesale site and can get free shipping for even more plugs than I purchased with 6 911 plugs thrown in for $50 total (1.76 each) Nuthin' but "mark up" ('cause they can)...thanks for getting me back on track!

phew!! my wife bought stock sparkplugs for her subaru..from subaru. $20 each! when i got up off the ground after the seizure and then fainting spell..i went to my shop and bought the same NGK, and returned the ones she bought.

crazy. i run DENSO in my tacoma.

The Bosch plugs for my corrado were $15, here on pelican..... Stupid high strung little *****....

Depends on what you get too. The Miata specs iridium plugs that apparently have insulators made from billet unicorn horn.

I went with the V power NGK for about 30% as much. Turns out to be the same plugs I ran in my Integra.
