I have a 1999 dakota with a 5.2 and I was wondering if anybody had ever fashioned their own cold air intake or if they just knew a way to do it by re-routing the intake pipe or something like that.

 

Lots of videos on you tube for home made cold air intakes. Won’t do anything performance wise. Just makes noise.

 

It'll make it more efficient and have better throttle response. I know what to expect, and it's not much, but it'll be worth it.

 

Clean up the top of the throttle body as well. Maybe bore it out to 50mm. (don't need to change throttle plates for that size.)

 

Thanks @HeyYou I've been looking at a throttle body spacer and 1.7 roller rockers but I've opted to start with a cold air intake simply because it's a cheaper option. I am looking to bring my engine more power by making it more efficient, giving me more power and even slightly more mpg.

 

Throttle body spacer does nothing. Aside from lighten you wallet. (which may give you an additional .00001 second off your quarter mile time.....) They are designed for wet-flow system. (fuel AND air) On a port fuel injected engine, that don't do squat.

The roller rockers will get you about 10hp/tq across the board. Makes you cam think it's bigger than it actually is, and is computer friendly.

Headers will nicely compliment the rockers.

Adding power to get better gas mileage simply doesn't work. You like the extra power, so, you tend to have a heavier foot. Maybe you have more willpower than I do.

 

Thanks for the advice I'll take a look at all that.

 

Good luck.
