hi, I want to know the difference between this intake and the 77-1563KP?

63-1563 provide estimated HP(?): 17 HP@ 4944 RPM while 77-1563kp provide estimated HP(?): 15.01 HP@ 4500 RPM. Also 77-1563kp has Aluminum Tube

I'm not convinced the specs are not identical. Although i haven't found separate charts to prove that. It really sounds like marketing numbers 17HP @ 4944 and 15.01HP at 4500RPM might be identical at both products if you find a curve for both products.

Check out the K&N; website. It lists the 77 model having an aluminum tube BUT 2 less HP and costs more! At find of day, I'll take $$ in my pocket and more power.

The 77-1563 advertises a 23.4 lb-ft gain in torque over stock at 3,661 RPM. The 63-1563 advertises a 15.45 lb-ft gain in torque over stock at 4,400 RPM. The 63 produces a 17 hp gain, but at a loftier 4,944 RPM versus the 77 at a 15 hp gain at 4,500 RPM. For 2 less hp, I'll take more torque at lower RPM's.

The link given by Straker has some incorrect information as it claims 733 "shifts more air" than 660, while the opposite is true. 733 = 583 CFM; 660 = 584 CFM. Since they move the practically same amount of air and 660 is lighter and quieter, I would say 660 is better.

The intake is at the bottom - a 1" by 2" area. In the main picture, it's on the lower right hand side (it's not easy to see).

I cannot say specifically. I just replaced a 65 with a 65A. Dimensions ate the same and all of the fixtures lined up with my existing piping. Very satisfied with my purchase.

this is either the 500 or 500xt. i believe the difference is the load stops either not included(500) or included(500xt). when i bought mine the load stops were NOT included. best bet is to ask the seller.

The intake only supply more air to the engine don't change anything else, it should not affect your smog check.

Can't seem to find any difference between the two. Both come with 2011/136x/115x part. Both look visually the same, both have the same pump. Perhaps just a different naming code from the factory? I would buy the $50 one. I have it, and it runs like a beaut.

Yes, sense it has nothing to do with emissions this is strictly an an intake it does nothing but increase airflow. youre header back system is what deals with emissions

To be completely honest, I don't know that there is a difference. At first I thought the motor might be a bit stronger in the 1700, but they both say 450 watt. Sorry I couldn't help any further than that.

Not 100% sure, since the K&N; site doesn't show this intake when you search for the M37. That being said, they are the same engine, so theoretically, it should work fine. There may be some spacing differences since the front is likely a bit larger, but that should be ok, as opposed to using it for a car with smaller engine bay, but even still, it's also the same engine as the 370 and that's a smaller car than the G. I compared it to the two Stillen intakes and their site shows two different models for G37 and M37 but pictures are the same. I think you'll be fine. Could call K&N; to be sure and they'll probably be able to tell you. Sound is worth the hassle. Not 100% sure, since the K&N; site doesn't show this intake when you search for the M37.

the difference between these two is one is 1600.1 and the other is 1500.1 and they are both great amps, CEA compliant if you feed them the power they want they will put out their rated RMS and some. I say go for the 1600.1 it has 100 watts more

I'll assume the fan is quieter, but in both specs the fan seems to be the same. Old Model (the one I have) is 1700RPM, 29.75 dB(A) with a max airflow of 59.05CFM. This matches the manufactures site specs for the Quiet Edition.

Josh, the intake side measures 32mm and the air box side is 43mm. I hope this helps!

I installed the cat-back and intake on the same day so it might be different with only the intake but I noticed a 2-3 mpg gain after I got over getting into it all the time cause it sounds so good.

damn, i'd like to know this too. specifically, which one runs quieter and cooler? and furthermore, which one is more reliable?

It will make a performance upgrade but at close to 4000 Rpms you'll feel a little more power , but with cold air intake it's usually good to put throttle body spacer mass airflow sensor and other intake upgrades to go along with your k and n cold air intake

I am not sure if this is a mounting measurement or the intake side. I would recommend getting one that is the same as you have.
