Product was inexpensive and arrived promptly. Weird how it was cheaper to buy 4 of these individually (with free shipping) than it was to purchase as a 4-pack though. Performance increase was immediately noticeable on my 2003 Yamaha Roadstar 1600. Excellent purchase.

Iridium Spark plugs are great, and NGK makes some of the best. They do add a little power and mileage, but the reason to use iridium plugs is for their longevity. I found these on Amazon for the best price I could find, and I needed 4 of them (NGK DPR7EIX-9) for my bike (Vulcan 1600). I was comparing prices on Amazon, and found that if I ordered 4 individual, they were a few dollars less than buying a 4-pack, and they had free shipping, the 4-pack didn't. So compare things before you buy.
good product,

Good product... I think! I personally did not see much of a difference in performance but I must admit, i was not expecting any. I drive a 1700 c.c. Yamaha Road Star so it would be difficult to see a difference given the size and power of the engine.
As for this Amazon seller, i would definitely recommend. The product was delivered promptly in excellent condition.
