    question about fuel injectors

    when income taxes come in i was planning on having all the seals in my motor redone cause i have an oil leak in the rear main seal but i was wondering if putting bigger fuel injectors and a cold air intake would give me any noticeable power gain. i dont really wanna turbo it i just want a stock sleeper i guess. any help is greatly appreciated

    just throwing bigger injectors in for no reason will not gain you anything, stock injectors work fine.

      More fuel does not equal more power.

        I don't think you need to consider injectors until you have gotten into some pretty radical upgrades, like forced induction or an insane cam. Honestly, I don't know if CAI really gains you much more than a nice clean look in the engine bay.

          The gains to be had from an intake are minimal. The stock airbox and tube flow pretty well.
          If anything, I'd suggest an SRI over a CAI. Easier to install, easier to remove when you need room in the engine bay, and you don't have to cut a hole in your sheet metal (which will rust... and that's a very difficult spot to repair!)

            Increasing the size of the fuel injectors without changing the ECU or tuning will decrease both your performance and your fuel economy. This is because the computer only controls the fuel injector pulse width, not the amount of fuel injected. So, with a larger injector, more fuel will be injected during open loop operation and your engine will run extremely rich. On a naturally aspirated engine, power actually decreases with air/fuel ratios richer than about 13.5:1. Not to mention the loss in fuel economy.
