I'm needing help with finding a reputable vendor that sells Mopar M1 intakes for my 99 Dodge Ram 4x4 with a 5.9 v8 magnum under the hood. Any help would be much appreciated. I'm kinda new to the forum so any advice is welcome.

 

Trying to find an M1 intake is like trying to find an honest politician... Look long enough, you might find one.
Your next best option is to buy a Hughes/Edelbrock airgap FI (fuel injection). They don't flow quite as much as the M1, but are still world's better than the stock kegger.

 

Unless you're racing, the difference between an M1 and an Airgap FI will be negligible .

 

^^ best answer right there.

Stacked side by side on stock engine, the M1 is far and above.

Tuning will either level them out or be even MORE separation...M1 being the better.

But yeah...few and far between.

 

If you haven't seen this already it's worth a peek.

One thing I saw on some dyno tests was the M1 produced less torque even than stock and only marginally more power than the airgap on a stock motor.

 

This guy has 4 barrel M1's. He machines fuel injector bungs.

I bought one on Ebay a while back (the thing was never used), took a lot of looking, but I found one. You just have to keep looking.

looks like jegs still has new ones...

 

Good luck with that one, it looks like you'd have to call JEGs to order it, makes me wonder if they don't really have it.
