spark plugs

Recommended Posts

After 169,568 miles, time for plugs. Any one else have lots of corroded under hood hardware, fuel rails, etc?

Granted, I am in the upper mid-west, the van spent the first part of its life in the Chicago metro and Madison, WI areas. Winter? here's your salt....(or brine) Looks like low quality plating on the hardware..meh.

 

Plug condition was a nice light brown/light gray - clean burn. The gap? Epic. largest measured .116, 'twas time, indeed.  New NGK 4469 Iridium IX plugs went in, night and day improvement, my butt-dyno says there are more beans on the fork.   Hoping to see a small bump at the gas pump, every bit helps. As for the corrosion, when I finished the plugs, I hosed everything under the hood down with SeaFoam Deep Creep (except the belts and exhaust) hopefully this will keep the oxidation to a slow crawl.  

 

Psst, Nissan, use better hardware...

weekend road trip 288 miles saw 15.5 mpg, up from 14.6, if I keep my foot out of the loud-pedal, I might be able to squeak more out...however, it is still a 9'3" tall brick of Monterrey Jack cheese, with a sloping forehead.

 

Next up, Gale Banks Exhaust, anyone on here have experience with adapting one from a Titan?
