Most popular I would say is the JWT popcharger...do a search the other options are out there. A lot of people also went for the K&N CAI intake or the NISMO CAI. Stay away from the AEM however, a lot of people have complained that it is not very good, and it can even lead to a loss in HP and TQ.

The JWT Popcharger is the cheapest out there and will give you the same gains as any cold air intake.

Next to that are the Injen and the Nismo, which are a little more pricey.

The differences between any aftermarket intake and stock will be dismal. The only thing you're really going to notice a difference in is sound.

JWT popcharger by far. Also depends on if you are going for looks. None of the intakes will really make any performance difference. Besides JWT I would either go Injen or K&N CAI.

Agreed and overpriced also. Go with Injen, JWT, or K&N

But something to keep in mind is that even though the Nismo is overpriced and probably loses power, some dealerships will still honor the full warranty (at least mine did). If you're looking to save money, or get more power gains, the popcharger seems to be the way to go. For the peace of mind, I went with the Nismo.

If you ever have any problems, the Popcharger can be taken off and replaced in 5-10 minutes, whereas a cold air will take longer.

Plus, warranties are not affected unless Nissan can prove that the modification directly affected the problem. I cannot think of any way that an intake could hurt the car.

Whats the BEST intake out there? (I dont care about price. Dont give me any bang of the buck stuff please.)

What intake in the market dynoed the most horsepower gain?

Anyone have an intake comparison link/issue? if there is anything like that out there. That could help.

There is no real best intake out there. Every one makes such minimal power gains that it can almost be +- error on each dyno that has be given on each one. There is a comparison out there and from what I remember JWT and Injen showed to be some of the better although neither make any signifigant gains

Rumor has it that Crawford has said that (with their new plenum) the popcharger yeilded more ponies.

If you're doing extremely extensive mods to the intake of your Z (upper and lower plenum, ect...), then I would talk to the manufacturer of whatever parts you will be buying in the future (Kinetix, APS, Crawford). They will point you in the right direction.

I think Dave said it best though...you're not going to see more than 4-6 horsepower total. Injen and JWT are said to be the best though.

Ok Im now considering the JWT intake, SPL air intake pipe, with a varis intake duct. Still dont know much about intakes but thought this looks like an awesome system.

Advice? opinions? suggestions?

Need help with what?

I haven't seen the SPL pip, but it's probably not any better than stock, and I've heard that the Varis duct doesn't get air there any better than without it. Plus, I think it looks kinda goofy on a lot of cars (looks good on some).

The best intake is the stock intake with a replacement filter like K&N or ITG. Unless of course you are going for cosmetic or audible enjoyment. It's a proven fact (wether you believe it or not, unless ECU is reconfigured) that you will lose power with aftermarket air intake. Air intakes are amongst the biggest gimmicks in the aftermarket industry today in regards to performance gains, they're a guaranteed performance loss, not too mention voided warranty and possibility of sucking up water (valve or no valve) and destroying the engine. So unless it's cosmetic or audible grace you seek, keep it stock and purchase a replacement filter.

Actually ChazzG has done a huge write up on these with Dynos and technically they dont make your car lose hp except maybe for a couple of them. I believe AEM may have been one of them. Can anyone find this. I cant seem to find it even in a search.
