Denso IK22 are 1 step colder $50/set
Denso IK24 are 2 steps colder $50/set
NGK Iridium BK7ER are 1 step colder $45/set
NGK Iridium BK9ER are 2 steps colder $45/set
Autolite AR3923 are 1 step colder $20/set
Autolite AR3934 are 2 steps colder $20/set
Autolite AR3932 are 3 steps colder $20/set
Personally, i have used the IK20's (stock heat range). And i have used the Autolite AR3932's.
I never had a problem with either. The autolites are a copper race plug. They are about $2 each. I ordered mine from autozone. They usually have some in stock.
The autolite ones are actually a very good plug. I rank them the same as the denso's and the NGK's
