AEM Fuel rail

[cfbate]

Hi Everyone,

I'd know if anyone has installed such system and what were the results? was the investment worth? did you have to reset your ecu? i am planning to purchase for mt 2003 crv and am deliberating on what the gains would be fo such an investment. my crv is stock with a k&n air filter system.

thanks

You get no gain, none at all, from upgrading your fuel rail.

Aftermarket fuel rails are made available for modified engines that will require extreme amount of fuel and fuel pressure. And even the stock unit can take care of quite a lot of pressure.

Fuel rails are only required once you get into the realms of Superchargers and turbo's. Simply dumping more fuel in your cylinders won't do much other then dirty up your engine due to bad combustion (fuel without air is BAD) by virtue of a rich running engine. That said, a fuel rail alone may still not work effectively without a fuel pump that can deliver the amount of feul required. In some cases the stock pump will do, in most it won't. Last but not least, pushing fuel to an injector that can't release it will do nothing for you either.

In other words, unless the fuel rail is part of a more extensive engine upgrade, you are wasting your money. If you are looking for performance upgrades, I recommend you start with:
- Honeycomb grille (creates a more direct airflw into the stock intake).
- Aftermarket filter (many like the K&N filter).
- Cat Back exhaust system.
- Aftermarket Intake (Both SRI and CAI applications available).

Hi Paul,
