Where's your other thread? I could swear that the car runs worse than stock as well! I deleted all of the resonators, including those on the snorkels. For anyone thinking of resonator delete, I would recommend not doing it. Can't be sure though, as I'm using Unichip with a "stock cai + dropin tune" The problem may be that the tune isn't right anymore because it's a modified stock intake.

#215 on this thread. I will test it out, I'm collating MAP, MAF data for the road and dyno and dyno power data using different resonator configs. I will undoubtedly just put the main resonator back in and, fingers crossed, that will restore the stock airbox's performance.

I think a good comparison would be to test the STOCK intake (with aftermarket filter) vs. a complete aftermarket intake system, on a car with exhaust modifications.. after alot of hard driving.

Is it possibly that's where there'll be a difference in power gains on an aftermarket intake, especially a CAI..? Maybe the stock exhaust is SO restrictive, it really doesn't matter what intake you have on there.. But when you start modifying the exhuast to allow more air to move through the engine, the better intakes will start to show a little more gain? I'm no expert, just interested to see if there's more of a difference on more heavily modified car.

IMO, doing I/H/E isn't heavily modifying and I doubt that even then the OEM setup is a restriction. Once you start increasing engine capacity and/or changing cams then it may well be worthwhile to improve the intake.

Surely there must be some cars with exhaust, remapped with both CAI and stock box?

'Heavily modified' is the wrong term.. more like heavily bolted-on modded is what I meant. But the OEM setup is pretty restrictive, especially considering the 2 cats on the exhaust system. The engine is just basically an air pump afterall.. it can't draw in more air if it can't spit it back out at the same rate.

Restricting the exhaust might possibly restrict the intake as well is all I'm saying. So if you put in a more free-flowing exhaust system, maybe the better intakes will start to show themselves. But I didn't do any before & after air flow tests of my intake with my other mods, so it's just conjecture at this point.

as stated plenty of times before front bumper doesnt have to come off to install or serve the filter in our intake

I have mine deleted plus a custom tune.... My car runs perfectly fine. Maybe you should find a local tuner and not run a base map. I hate it when people make speculations w.o data to prove "it runs worse" I would personally recommend doing it because the car felt better to me and my led foot.

I'd actually go as far as saying that the cats are only slightly restrictive, but for the time being I'm not on about the exhaust but I understand your point. Although swapping the front-pipe out doesn't create a huge jump in power, although I know it does help.

The opening of the stock air feed in 60mm, if you look at how much power a 60mm TB can support (It's well above 200hp BTW) then you have an idea of when the stock system becomes a restriction. I know the routing is more convoluted than a CAI but that will just change the power curve rather than choke the engine.

@NickFRS, I have to agree with @BuBlake that I feel the same. I don't think it's down on power though and I will dyno it to likely prove that, I just feel that at part throttle applications it's no where near as good as it used to be. I also have a custom tune BTW.

That's awesome! How do you do it?

Unscrew the TOP and SIDE (wheel well) bolts/screws of the bumper, don't bother with the ones on the underside.. You can pull the top portion off & away from the frame far enough to install the intake.

Especially if you opt for the long body K&N filter (which has 30% more filter area than the aem dry flow) :thumbsup:

my intake came in yesterday. quality looks great...there does seem to be a lot of loose metal dust inside the piping. going to have to clean that out before it gets installed.

I have the Fa20 CAI with the AEM filter.

Pulled the bumper for the install as I was doing some other mods that required the bumper to be off the car.

I also have a Fa20club tune.

With the tune there is more power/torque at every rpm. The dip is flatter, but not gone entirely. The car sounds great from 2500 rpm and up, really a lot louder than stock. Install was pretty straight forward with the exception of the PVC hook up. I had to get a 90 degree fitting (Ford PVC) from Autozone to connect the PVC hose to the intake.

I have tracked the car as well and absolutely no driveability issues there or on the street.

Well worth the price of the intake.

I'm also running this intake and the FA20Club ECU tune. Like a whole new car. I highly recommend it. Not the prettiest intake but I think it's the best design.
