Default GravelSports CAI reviews?

Hey all, well I know this is kind of unorthodox, asking for a review rather than posting one, but I'm looking for people to tell me about the GravelSports intake unit available at PKZero ( http://www.pkzero.com/NA_Parts.htm ).

Here's their pictures:




It's a $300 unit. So it's in Cobb CAI price territory. Higher, actually, but with those kind of looks and if it's as practical as it is described to be, I'd certainly be interested in the future. Searches yielded a little, but not much that's either useful or friendly to read... primarily: http://forums.nasioc.com/forums/show...hreadid=276400 .

Thanks!!!

Thumbs up

Hi Siper2,

Those shots are of my car, so I sure can't give you an unbiased view

But I will say that I love the CAI! I didn't notice any of the loss of torque that many CAI's have and there is definate improvement (not just butt dyno here) with upper-end hp. I have no dyno's of it but I can give you an example.

There is a place between my house and a friends that I travel every week at around midnight, it's a new highway that isn't completed beyond a couple exits, so I always take the opportunity to have some fun with my car. My exit and my friend's exit are separated by one other, so I have maybe a mile or two drive. I also have the Cobb cat-back, too and underdrive pulleys. With just those two mod, I could get up to around 110mph before I got to my exit. A little more, maybe less, depending on other stuff.

When I put the CAI in, I could easily get to 120 and would sometimes get to around 130, usually though just the low-mid 120's.

Right now I have the pulleys and CAI off (it's going through some warranty work) and with just the cat-back I am only getting to barely 110mph right now.

So without a doubt, it's giving some nice power there!

Also, the sound. It has a very unique sound to it, very high-pitched for a CAI, very mean and aggressive, like a race car, when it gets to about 5500rpm... at 6000rpm it becomes a beast and is better than any shifting light! But during normal cruising, there's no difference in sound from stock.

And finally, there's the cool-looks factor.

So to sum up: I give it two big thumbs up!

Now I understand . You have this intake installed on a 2002 2.5. I thought you had a 01 or prior with the hood scoop that intake was designed for . Then you would probly have a rain problem . or for that matter a tru CAI. As it sits you are still pulling hot air under the hood .

I have an hood scoop! You cannot use this without one. Otherwise, as you noted, it would be a HAI

Unless you're in an amazing downpour, rain shouldn't be a problem as the intake getting wet isn't a problem but rather submerging the intake in water is. I live in southern cali so the little rain we get is never a problem.

Hmm, however, I live in New England, so I wonder if it might be a potential issue? That's what's been steering me away from the CAI thing, the whole water issue. Huge puddles aren't often, but they happen. A lot. And I don't want to be up the creek just because I wanted to put a funky pipe on my engine.

I've opened the scoop on my car, so if I bought this unit someday, would it be wise to close the main scoop and maybe just leave the vents open?

From what I've seen of the design of this intake, it looks like any rain/snow water coming in the scoop would either be repelled by the filter or be negligible to as far as effecting performance (you can have small amounts of water go through the engine without damaging it).

If you have torrents of water coming up over the hood of your car...you have bigger problems than a hydrolocked engine...like HELP! someone get me out before I drown!

Word.

Hmm... true....

However, while I know "common" CAI designs like the Cobb unit take air from the fenderwell, some don't even USE a filter, it's more or less a straight pipe system. Or, well if there is some internal filtering or whatever, it doesn't seem it'd do as good a job as this GravelSports unit.

So while I understand that direct rain is possible from the hoodscoop on that particular unit, a deep puddle is a big threat to the others, so....

...which is better/worse?!?

Yeah, with this one you could basically drive through a river as long as the water doesn't cover the hood!

Is the filter a washable type filter .... like K&N?

Does the air flow directly into the Throttlebody or does pass thur the tube on the side.

I'm a nubie to the subie world, so please excuse me if this is obvious.

Thanks in advanced

The air filter is the stock filter. You can use a K&N or any other filter that works with the stock car.

The air goes from the box around the side and underneath to the throttle bottle. This is important to keep the right amount of volume of air between the filter and throttle body (keeps that dip in torque from occuring as does in many aftermarket intakes).

Hope that helps!

This intake looks like the most appealing one on the market for those of us who don't have intercoolers behind our hood scoops. I am still waiting to hear work on a my98/99 tested version.

Bah wuss, I've had water/mud coming over my hood before. All it takes is a decent puddle and some speed. Hell I've gotten water on the roof! (Note: I'm deleting this post if I ever sell my car. )

All intakes use a filter, I promise. There is a difference between this intake and fender intakes. Fender intakes only have a problem from sustained water. The top mount can have water accumulate on it. This probably won't be a problem for most people, but crazy persons like myself have to take such things into account.

Any more reviews? Thoughts? Dynos?

I'm very close to purchasing this intake, but would like more feedback.

I've got this intake and I love it! Obsidian pretty much covered everything positive about this intake.

I too live in So Cal so rain isn't really an issue. I have driven it through some heavy rain (a rare moment here) and took a look at the filter. It was dry, and so was the intake itself. It seems that the distance from the filter and the scoop is deep enough to prevent water from really getting in there.

I've directly shot water onto the filter (via garden hose) and started it up. No problems. As long as you maintain the filter and keep it from getting submerged, you'll be fine.
