NGK Iridium Spark Plugs

NGK Iridium Spark Plugs

We now carry the NGK iridium plugs in heat ranges equivalent to the Denso IK24 and IK27 plugs. The NGK BKR8eix is comparable to the IK24 and the BKR9eix is comparable to the IK27. The BKR7EIX-11 are comparable to the IK22, more in the stock heat range. Get the same spark performance for a little less.

Note:  The main difference is heat range: the BKR8EIX is a colder spark plug than the BKR7EIX. This means the BKR8EIX is better suited for high-performance or heavily boosted engines that generate more heat, while the BKR7EIX is for lightly modified or standard engines operating at lower temperatures.
