Which is best for the IS and wot is the difference between the denso ones and NGK ones?  ( apart from the price)

I just put some denso iridiums into my gs (IK16's) and can heartily recommend them alot smoother running with these in will warn those with the 2jz engine they are a bit of a swine to change though.

just brand difference... some car companies prefer a certain brand over the other

Denso was the first manufacturer that came out with the iridium design, and is regarded as the leading company. Many aftermarket specialists such as HKS are using Denso for their high performance plugs

NGK has been playing catch up with Denso, and also have the iridium technology, but in order to conquer market share, their prices are lower than Denso.

Some people think that Denso are better than NGK .

The Denso iridium plug types for the IS are as follows:

IK16: IS300 (these are high performance plugs and should be changed @ 30K)

IK20: normally aspirated IS200

IK22: Supercharged or Turbo'd IS200 (these are high performance plugs and should be changed @ 30K)

Q. What makes iridium better?

A. Until recently, platinum was considered the best material to use on the top of an electrode because of its durability. However, iridium is 6 times harder, 8 times stronger, and has a melting point 1200 degrees higher than platinum. Put that into a harsh environment such as an engine piston chamber, and you have a spark plug that can resist wear much better than platinum. Additionally, the DENSO iridium Power alloy is so durable; it allowed our engineers to produce the world’s smallest center electrode (.4mm) which reduces the voltage requirements, concentrating its sparking power. Also, its smaller size, combined with the tapered U-Groove ground electrode, allows more room for the flame kernel to develop and produce a more efficient combustion.

Q. How long will iridium Last?

A. iridium use represents the most significant technological advance in automotive spark plug manufacturing, since platinum was introduced in the early eighties. As vehicle manufacturers produce increasingly complex and efficient automobiles, there is a greater need for long-life plugs that can tolerate leaner fuel mixtures and improved combustion processes. DENSO has responded to this need by developing its iridium alloy, originally for OE applications. For example, many newer Lexus’ and Toyota models carry an ultra long-life iridium plug variation (.7mm with platinum tipped ground) that is capable of up to 120,000 miles of service. DENSO iridium Power plugs, with their .4mm center electrode, have been developed for performance applications. Because gradual wear will “round-off” firing points over time, the concentrated firing power and voltage requirement benefits will be reduced. For this reason, DENSO advises replacement after 30,000 miles.

Q. What kind of performance will I get from this plug?

A. Generally, you do not purchase spark plugs for performance enhancement. While DENSO iridium Power spark plugs have contributed to numerous accomplishments through dyno-testing and actual use, their true benefit lies in their efficiency, durability, and improved firing power. Serious tuners modify their vehicles by increasing boost through turbo-chargers, super-chargers, and Nitrous. They are also known to add high-energy ignition systems, tinker with timing, adjust fuel mixture ratios, and increase horsepower through other means. Putting these kinds of demands on their engine increases the need for an efficient, durable spark plug that can handle these kind of harsh environments. That’s where DENSO iridium Power can make a major difference.

Denso where once Toyota and they still own around 20% of the company. Denso IK range of performance plugs are probably the best you can get. HKS and TRD rebadge them.

Sorry to take this off topic slightly guys but what are the IK27's for?

And which Denso plugs are the equivalent of the HKS plugs? I was under the impression that the HKS Racing plugs were the same as the IK20's which was why I originally fitted IK20's when the SC was fitted?

Thanks in advance, that's a superb price Steve, can I get two sets please mate?

Does anyone know what the deal is with the group buy on these???

I have joined the group buy early last week for the 6 denso plugs but I need the plugs asap. I have tried to contact Steve who is organising the group buy but I don't know if he has got the PM's yet as I have had no reply! :crying:

I need to know if there is a time limit to how long this Gb will last and if it is too long for me then can I get my name taken off the list for the group buy as I will have to get the plugs elsewhere! :blush:

help on this would be much appreciated from Steve or someone who knows more about this!

Thanks.

I know that the number has to be reached but what if it takes weeks for it to be reached or if it is never reached!!!

I need the plugs this week and cannot keep the car off the road just to wait on plugs!!

The problem is that I know there is some sort of commitment issue when you join the group buy and I don't want to just leave the group buy unless I have to!!

I need to get some answers for this please from anyone that knows asap or I will have to get the plugs myself!!
