After testing numerous spark plugs we found the absolute best plug money can buy. Trying to find an adequate plug colder than the PFR6B-11B proved to be tough, but these plugs deliver the best spark around. BKR6, 7, 8 and 9.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHeat Ranges Available:\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe \"8\" heat range is also a great all around performer. Allows one to run higher boost levels than 20+ safely, yet is hot enough for daily street use. Perfect plug for California style climates all year round. Works good with low nitrous shots too.
