The denso are a good brand to go with.....
I put on set on and was very well pleased with them
My idle was smoother and acceleration seemed to improve.
I dont really know about the fuel ecomony that they claim.
I could tell any differece in mileage.............

I highly recommend them ............ (get one degree colder than stock)

HKS plugs

One of the people that I talked to at Denso, said that they make the plugs for HKS. They said that it is the same plug, except that is has the HKS logo on it......and costs about twice as much.

One thing to consider is if u get any detonation at all copper plugs will have a chance of doing very little damage or none and irdium will mess u up big time.

This topic was bantered about big time over the last few days on MKIV forum. Go to that for a lot of info. What technical facts does 3L base his opinion that for some reason detonation with iridium plug will screw up a car and copper you will not. Detonation will screw up a car period. The answer on MKIV after a lot of back and forth was no one plug, plug #, etc. is the magic bullett for the Supra. It all depends. I have Denso Iridiums and I like them. One objective test that I did read in a turb import type mag was putting Denso Iridiums in a BPU Supra and putting it on a dynojet. The car on the plugs alone generated about 10rwhp more than stock. Nuff Said.
