Stock Denso IK plugs.. love'em.. last a LONG time, just lose they're peep of a 'new plug' after awhile... but they'll keep going strong long after. Oh ya, expensive f'ing plug!

I use IK20 in my 3S-GE. The last set lasted about 75.000 Km. They are good, I got not pinging (fundamental in an FI car), a little more power, instant acceleration. Deffo would keep on buying as long as I can afford them

denso heat ranges are 3X ngk heat ranges

like an ngk range 6 would be a denso ik18
ngk range 7 would be a denso ik21

so denso has a greater choice of heat ranges...

so an ik20 is like a range 6.5
we usually recommend a heat range 7 for 5sfte's , that's why i said ik22
