OK folks, here is an economical place to order the NGK BPR 5 ES: http://www.race-mart.com/items/products/ngk/NGKBPR5ESSOLID-detail.htm Their phone number is 888-286-9797 and I talked to Paul there. Be sure to specify the "solid top", not the threaded top. They sell them at only $1.65 apiece, but you have to buy them in a 10 pack and there is a $25.00 minimum order. So you end up with 20 plugs for $33.00 + shipping - not bad. And I'll pass along the following commentary about the NGK BPR 5 ES from someone who gets seriously into this sort of thing ------- Hi Keith, The BR5ES (BPR5ES for resistor plugs) are one heat range colder than NGK's catalog recommendations, but I have no trouble with any fouling or misfiring in either my early Hemi or LA-engined vehicles. The slightly colder heat range can help eliminate detonation problems in hot weather with today's fuels. The rule of thumb I learned on heat range has always been to err on the side of a colder plug if drivability and plug fouling are not a problem. I've used this general rule for race engines in hydroplanes and race cars as well as vintage cars, with good success. Now the caveat: Lisa and I put a lot of miles on our various vintage cars (occasionally at extended high speed!); they never see service just loading and loading from a trailer. These cars virtually always go through a full heat cycle every time they are started. So...if a customer's car is used primarily in display and low speed cruising, a hotter plug might be necessary to get a good, clean burn. Also, a car that has a tired engine and suffers from excessive oil consumption will require a hotter plug.
