1992 Acura Integra

We test late-model low-mileage cars most of the time. You can tell from our test results so far that 2000 was the earliest car we've tested. I do get asked how the plugs will work on an older engine so here it is, a car that has 107,987 miles on the odometer going though the ringer.

With new stock plugs installed we got 144 horsepower at 6100 rpm and 138 Ft-Lb of torque at 5000 rpm. Acceleration from 40 tp 80mph took 14.35 seconds over a distance of .24 miles and the engine ate 1039.47 cc of fuel on the fuel economy trace.

BE-1 Pulstar plugs set to a .044" gap and installed to a hot engine brought power up to 151 horsepower at 6100 rpm and 143 Ft-Lb of torque at 5000 rpm. Acceleration dropped to 13.51 seconds over .23 miles and fuel consumption also dropped to 978.15 cc.

So how did an engine that has almost 108k miles of wear on it fair? We gained 7 HP(4.86%), 5 Ft-Lb(3.62%), decreased acceleration time by .84 seconds(5.85%) and increased fuel economy by 5.9%. Not bad, not bad at all.
