Had some time so I changed my plugs.

1. When I changed my OEMs, throttle response was still there. 30K

2. Tried Bosch+4...THEY SUCK, one of my coils was wrecked and cause hesitation, coughing, like the fuel lines were clogged. changed out in 5 days.

3. DENSO Double Platinum...are OK but the car felt so bogged down still not like it was with the OEMs. Out they went today and they were Dark. similar to the Bosch4s. Like the heat range wasn't right.

4. PUT IN NEW NGK OEMs! and my PEDAL and the RPM NEEDLE are "as one" again. Snappy, Responsive, Sharp and DEEP all the way into WIDE OPEN THROTTLE!... BUTTO DYNO was in effect and confirms.

NGK #PFR5G-11 and enjoy the ride

 

i had the exact experiance with my max back at the 60k mark. NGK Platinums are definitly the ONLY plug id go with, unless your Boosted or Sprayed.

NGK Platinum's are the best choice for Maximas.
