I recently upgraded the injectors on my 99 with ones from Precision Injectors. I've had them in for several weeks now and I'm happy to report a solid 2 mpg increase. The motor runs much smoother, is very responsive and requires less throttle input. Best mileage so far is 21.69 mpg's while fully loaded with luggage/tools and a passenger. I'm a happy camper........

Do they make those for a 96? I am thinking about upgrading since these have been in there since well......96.

I also have a 99. 5 inches of lift with 32x11.50 r15 tires. The swap took about a half out to install with new o rings from a local parts store. 10mpg to 10.9 mpg. Cheap upgrade with a decent boost of mpg.

Highly recommended

I wish i had 21 mpg like the orig post :P
