M1 inlet on it's own: noticable difference?

I should be receiving my M1 inlet soon and in anticipation of fitting it I was wondering if I will notice any difference at all on my 5.9?

If so what will I notice?

fuel mileage probably not .... power & torque depends on the specs.....
biggest difference will be in your walllet....thinner

you'll get a hp increase, powerband will climb upwards a few hundred rpm so it may seem like a low end power loss. mileage may increase slightly.

you can get a turtle to fix the low end power loss though.

Well that doesn't sound to enthusiastic...I was under the impression that the M1 was a pretty big important thing overall when modding the Jeep power-wise?

Yes, but often mods work together, and some aren't very effective on their own, but help another mod work better.

is the M1 the only performance mod you'll have on it?

if so, like already stated, you may not notice it as much. I had CAI, bored TB, full 3" exhaust, and tune before i did the M1 and i could instantly feel the difference. but i dont know how it would be on a stock engine.

The M1 Allows more air flow, so if your using a stock TB, your only getting in so much air, thus a bottle neck. Yes there will be some power gained, but the M1 is to be coupled with a TB and free flowing intake of your choice. Even then if you want your low-end power back a turtle is going to be needed for the M1. I'd rather suggest a stock intake thats ported or a "ported kegger".

Well I planned other mods as well such as a larger TB and headers coupled to a Kolak exhaust.
it just so happened that the M1's were in short supply so I thought I get one before it would be hard to get so to say...I do realise that mods tend to add up to eachother though!

I think you'll see more of an improvement than the others have said , If your intake is stock , the probability of a leaking plenum is extremely high w/o a hughes plate . The vacumn leak alone in a power loss . M1's have a one pc design , no plate , to me , that's worth the cost right there .

Your on the right track
