I have a 1999 f150, w/ 212000 km on the motor... 4.6L Romeo Block triton v8 w/ auto tran, 4x4, CAI, TB spacer, Edge Evo..

Injectors are starting to get a lil noisy... thinking bigger=better, still new to the whole triton v8 motor....

Would new injectors improve power and economy? if changing injectors wats involved? reprograming? any problem arrise with changing injectors?

 

Unless you plan on supercharging or some other power adder you should use the stock size injectors.

 

x2 to what anfo said. Bigger injectors will do next to nothing on a stock engine.

 

Throw the TB spacer in the trash and stick with the stock injectors.

 

Injectors are suppose to noisy - That means their working

I have the type 3 upgrades and their louder than mine stock ones were.

Hey jbrew what type are the stockers? 2? And if I upgraded to design 3 is it worth it? Like for performance and fuel mileage most importantly?

 

Type 3s make a little more noise than stock and the place I notice the difference is at idle, alot smoother when your hand is on the steering wheel.
