Hi all

I put some Denso IK27 spark plug in my 3 door and it runs so much better. I have been through many a spark plug thread where reputable engine tunners/mappers give them high praise.
I have been on the Denso website and it states that the gap is 0.8mm and gapping them can damage them as they are not designed to be gapped. So my question to tunners/mappers is, do you use them as is (0.8mm) for up the 350bhp on a yb running a dizzy? If this is the case can they do 500bhp on factory gap?




Thank very much.

Tim.

 

Mine ran ik27's at 500bhp my gap was 0.70. Never had an issue with my plugs

 

Cheers ajamesc, did you run on standard ignition system?

no mines on autronic sm4

 

Ive just ordered a set for my 3 door, its got ik24 in but it bogs down when you floor it and they look oldish so im hoping this will cure it. Im running wasted spark, greens, t34.63, msd chip about 330bhp spark plugs gapped at 0.65

 

I've got ik24 in mine running 374bhp gapped at 0.65 best ones I've had in

 

Morning,

Sincossie, arn t the k24 a bit of a hot plug for that power?

Best.

Tim

 

I was told to get these by motorsport developments after a live mapping session seem to work fine

 

I had nothing but problems with denso plugs in mine, put standard plugs back in and it's been fine ever since
