I have bought several things off the GBC. My only complaint is it seems to always take awhile to get your order. I expect my order to go out the day it is placed or at the latest, the very next day. Anyhow, I will be ordering my plugs off there as I can't find anyone local that has them. I hate the waiting of online shopping. [IMG]i/expressions/demon.gif[/IMG]
the guys from JDM motors, the ones that are doing the group buy, sent me IK16's which he said are considerably better than the IK20's because one of the workers there put them in, who had the IK20's in before, saw a big improvement over the IK20s... i'll let you know in a little bit how it turns out...

I just talked to the guys running that group buy and they told me to go with the 5303 instaed of the 5304 plugs. Different numbers, now I'm confused. Price was $48 shipped.

IK20=5304
I wonder if the 5303 is a colder or hotter plug. I am also curious as to whether they are sold out of the IK20 and are recommending/shipping the other plug to fill the orders. strange
The Denso site recommends the IK20 plug.

IK16...5303....HEAT RANGE IS 5 COLDER
IK20...5304....HEAT RANGE IS 6 HOTTER......ALSO AUTOZONE IN THE EAST SELLS THEM FOR $12.99 EACH...ALITTLE MORE EXPENSIVE BUT THEY STOCK THEM......FOR THOSE WHO HATE TO WAIT !

If you ride hard, fast, and in hot weather (conditions where the engine runs hot): Use a cold sparkplug (such as a W5DC).
If you ride easy (moderate to slow) and in cooler weather (conditions where the engine runs cold): Use a hot sparkplug (such as a W7DC).
If you are an average driver use the heat range indicated in your owner's manual or the above chart....I searched the web and found this explanation....it's for motorcycles but the priciple is about the same for cars....the rest is trial and error and the way you drive...many factors to concider. I'm not sure which denso plug I would go with. Sure would like to ask that guy that has tryed both so I could make a better choice....hope this helps you.

When a plug is rated as cold, this rating is NOT a indication of the intensity of the spark. This rating is a indication of how well the plug can transfer heat from the electrode itself to the head. A colder plug transfers more heat from the electrode tip to the head, therefore the business end of the plug,(electrode), is at a colder temperature PRIOR to the time the ignition attempts bridge a spark between the gap. If this colder plug is sooooo cold, (its relative), that the fuel mixture can't be vaporized from the surface of the electrode and insulator, (from the heat generated from the previous strokes fire), PRIOR to the application of the spark, the potential that is supposed to jump across the gap will bleed off by conduction thru the wet surface across the electrode and ceramic to the head. The result is a fouled plug. And the converse, a plug that is too hot will retain too much combustion heat and tend to pre-ignite the fuel mixture before the ignition fires. This is pre-ignition, and causes detonation.(very, very bad). Just a few seconds at the rpm we run will cause destructive failure of the engine.
I'm researching DENSO right now on heat ranges, 6 may be colder than 5.... I'm not 100% sure and I don't want to pass bum scope! I'll post the right answer soon, if someone does'nt post the answer before me.
The heat range number located on the insulator indicates the temperature range of each DENSO spark plug. The lower the number, the hotter the plug; the higher the number, the colder the plug. [IMG]i/expressions/face-icon-small-smile.gif[/IMG]

All you'll need is a deep socket and an extension rod. I'm not too sure what size nut is on the plug though.

Just got my plugs today! They sent me the IK16-3503 plugs. I don't know why they didn't send the IK20s. I think they would need something better then their @ss test to go aganst the factory's recommendations. They may just be out of IK20s if you ask me. Anyhow, I am going to install them in a little bit.
Are these pre-gapped or do I need to make it bigger, smaller, or just check to make sure it is at .44?
I am about certain that the denso site says they are pre-gapped.

Well, I checked mine befoe I installed them and they were all at .044. I guess they don't need to be. I was very surprised. When I have bought plugs in the past, the gaps were all different and had to be set. I just left them alone.
The engine seems to run more smoothly and pull more smoothly with a little better throttle response. It could just all be in my head though. I am waiting to see if my mpg improve any.
