4 New NGK Iridium IX Spark Plugs Suzuki GSX-R1000 2001 02 2003 04 05 06 07 08 09

Replaced the plugs in a newly purchased 2007 gsxr-750.The plugs in the bike were used but good condition cr9e - the non iridium version of this plugWhile the iridium versions do not affect performance, they do have a much better life span.I went this route so that I will not have to replace them again while I own the bike.However, getting rid of the old plugs did provide a much smoother off/on throttle switch (no longer jerky when getting back on throttle during deceleration)

Direct fit for my 03 Gsxr 1000. The ignition coils were corroded and the caps were stuck in there from the old plugs, so j removed the caps from these and inserted into the bike. No problems. Those with older bikes complaining of fitment issues even though it's the right type of plug might wanna check their ignition caps. Did give the bike more pep and runns smoother, but that's usually a result of a tune up anyway. Satisfied.

The new plugs made a huge difference in the performance of my 19 year old GSXR...

I upgraded to these in my Yamaha Jet Boat with twin MR1's. The motors are known to foul esp with long periods of idle such as through a no wake area or idling around the dock. Performance is the same as the stocks, but the Iridium's last at least twice as long. I am going on season 3 with this set, still running strong, no signs as of yet of any fouling. With the stocks I'm lucky to get one season before I start experiencing hard starting, rough idle, erratic rpm at speed, and loss of power out of the hole... Also no gap required, just a little anti-cease around the threads and they are ready to roll right out of the box.

Product came quick, fit my 2006 gsxr 1000. Started right up after putting them in runs good right now.

Good product

Perfect. Shipped extremely fast.

Haven't been in a long time. But so far performing well.
