Well here's an idea I haven't read so much about on this forum. Has anyone replaced their injectors with ones with more fuel allowance? I have no clue as how many cc's stock injectors on the 4Runner are, but I bet with the deck plate, ISR, and Amsoil mods done, the air/fuel ratio would be enough for some bigger injectors. You guys with superchargers have even more potential with bigger inectors. And then what would you all recommend for top-end spark plugs? I know Bosch's platinum 4+'s are damn good, but are there any other (less pricey) ideas?

Read Gadget's website. It will tell you everything you want to know.

 

I don't think you need larger injectors if you're still NA unless you put some massive cams in and improved exhaust and intake flow substantially. The stock injectors have been tested to be ~240cc and are good to approximately 220 bhp at 80% duty cycle.
