The no 1 spark plug for a 1992 K1500 pickup 5.7 liter engine is the Bosch spark plug. As of 2013, the average price of a Bosch spark plug is $64.99, plus tax and shipping.
I think it's .06 but if you get Bosch Platinum plugs, you won't have to worry about it.
Maybe R10 its the code production of that specific spark part number The reference number or part number is WSR6F (Bosch) BPMR7A (NGK) or WSR6F (Bosch) or W20MP-U (Denso) or RCJ7Y (Champion) are the same plug, but different brands.

NGK Iridium if you don't mind paying $9 or more per plug. I personally like Bosch and have Bosch Platinum +2 in my 92 Accord.
