Car absolutely SCREAMS like a cat under heavy throttle. As soon as you blip the throttle, you can hear the sucking sound from under the hood. The engine simply MUST be getting more air.

The install took me and a friend 2 hours. Whoever posted this as a 30 minute job was on speed, or had done a dozen of them first!

At any rate, it's in and I'm happy it's there

Got it from WAYMotorWorks.com, great service and great price, thanks WAY

The install took me 1.5 hours, by myself. I intentionally didn't rush through it, so I could be more careful. Better to take your time, right?

I too couldn't believe the sound difference. My gas mileage now suffers, just so I can hear that baby scream. That sound is addicting!

You made a wise choice in intakes, my friend! Enjoy!

 

I'm getting ready to install mine. Any tips or recommendation. What was the hardest part of the install?

 

When you remove the ram air intake pipe that attaches to the lower front part of the bottom of the air box pay close attention to how you twist it off. I spent about 15 minutes cursing when it came time to reattach it upon reassembly. It's a total pain the the a$$ but it will fit. Also, if you're intalling the Alta silicone hose as well it can be a real struggle to get the metal collar/clasp positioned in just the right direction to fit a screwdriver down there to tighten it up. I'm referring to the location where the silicone hose attached to the throttle body. Patience is key. The warmer weather will be a help too. I did mine in the dead of winter and was beginning to lose feeling in my fingers!

Good luck and enjoy the Alta CAI. The whine is simply intoxicating... and keep your eyes peeled for speed traps. You'll find yourself quickly exceeding the speed limit on many occasions with your foot pinned to the floor just wanting to hear more "music" from the engine.

Macman.

 

Thanks. I'll go over the directions and Webb Motorsports instuctions and pay special attention to the items noted.

 

So, other than the noise, any noticeable improvement in performance?

 

I got one myself from outmotoring.com (they have a sale going on) to see wat all this hype was about. I did the install last night, actually.

The hardest part of the install... keeping your hands oil free from when
you wipe down the filter's opening with de-greaser. it's a pretty
straight forward install. I too looked at Randy's how-to. It's a nice
set of instructions. It took me about an hour... (30 min spent trying
to find the damn torex screw I accidentaly dropped into the engine
bay when I was taking off the Pilo intake... )

 

Unfortunately, I only drove it 8 miles at night after the install. I have a JCW kit, so the performance gain may be a bit less noticible for me I think. On the other hand, 8hp or so is a lot for any of us.

 

My best advise would be to work carefully and take your time. Read the instructions that come with the intake AND the instructions from Webb Motorsports.

There were two snags for me: Getting the factory clamps off of the hoses either requires a special BMW $185.00 tool (which we had) or cutting them off. I got an Alta with a hose included and TWO new clamps came with the kit, plus the clamp on the filter. We needed THREE clamps to install everything in place, so we had to re-use on of the factory clamps. That would have been very difficult without the tool we had.

Snag two was simply getting the original air box bottom back in place. It just took some figiting.

Other than that, it's pretty simple.

 

Just slide the flat end of a spade screwdriver between the two metal pieces where they overlap on the clamp and twist. You should see a little raised space where they overlap and a small spade screwdriver fits in easier. One quick twist and the clamp pops open and is completely reuseable. Personally I felt more comfortable with new screw clamps from the hardware store though. Allowed for a tighter fit especially if you're using the Alta Silicone intake hose.

Macman.

 

As macman stated, you can re-use those factory hose clamps.
I too just used a regular screw driver to release, and a set of pliers to
clamp it back down (for the ram-air hose).

The stock airbox bottom is easy to put back in place if you put the
rubber doodads (as Randy states) onto the airbox bottom first, and
then just drop the unit where it goes and push the box down over
the mount screws. it should line up in no time (like no more than
15seconds).

 

NOTE:

Use the bag that the filter comes in to hold the filter on the box mounting point as you tighten the clamp. The filter is VERY oily, and you can keep your hand clean by holding it with the plastic bag.

MORE IMPORTANTLY:
Make sure you check the filter a few times in the days following your install. Mine had some oil on the inside of the mounting lip, and it caused it to slide off(!) after a few miles of my first ride with it on. It is crucial that the rubber circle that the clamp goes around is completely free of oil, so it doesn't slip off. Like I said, check it after each ride for the first couple days. Have a screwdriver handy to re-attach the filter via the clamp again, just in case.

yep, I did that too. :smile: the filter opening's got a ton of that stuff... took
maybe 2 papertowels and lots of RC motor spray (similar to brake cleaner)
to rid that oil from the inside of the opening and out before I clamped it
down to the heatsheild.

mine hasn't slipped off. I think Randy mentioned on his instructions not
to over tighten that hose clamp too. so mines only snug.

 

Bob////Margolis,
I am glad you are happy with your intake, and the install went smoothly. If you have anyone give you a bad time about your foam filter, have a look at this to help convince them otherwise.

Hopefully this will help you and some of the other ALTA intake owners out there, know they have the best and highest gaining HP intake on the market. And yes we stand behind our 12WHP (on a mustang dyno) figure.

 

Thanks Jeff, that's great information. I have two questions for you: 1. can you post the Dyno results graph here. 2. At what mileage, under average conditions should the filter be cleaned, and once it's cleaned, does it need to be re-oiled. What's the best way to do all of that?

Thanks,

.

 

YA, what he asked?????

 

Bob///Margolis,
It is hard to say what milage you should clean the filter. Things like the climate, dusty, stuff like that effect how dirty the filter gets. As a general rule, i would say clean it every 10k miles. Here is the graph.
Notice peak HP was 10WHP more, and torque was 6FT/lbs more. The midrange gained 12-14WHP and 10ft/lb. This has been very repeatable amonst other people that have dynoed their car. This is also on a Mustand Dyno which reads low numbers. Dynos like dyno jet will see more than this.

 

Have you done the same comparison with an '05 model?

 

I have a question on that graph - please correct me if I'm wrong.

The base run was done at 5:15:19 pm and the modified run was done at 5:20:30 pm.

So you removed the old intake system and installed the entire CAI in 5 minutes?

Or were both runs made with the CAI in place? If so, what are the hp/torque figures from the original intake system?

 

CoryB,
We preped the stock intake on the car to make the swap easier. Basically we remove the screws that hold the wall in place under the air box, and on the side, installed hose clamps on the tubes (so we could remove them easily) and as soon as the 3 base run was done we installed ours. With the correct tools in place the intake can be installed in about .5 hours starting from scratch. It really was pretty simple disconnecting the hose from the TB and removing the ECU/air box, then dropping in our filter/shroud/intake tube. This also makes the test very accurate doing it so quick.

This same day we installed our panel filter and got roughly 2-3 WHP and 2-3 Ft/lbs. Not huge, but some decent gain. Notice how long ago this was. To date their is no other intake out there that claim the HP and Torque we do.

kaelaria,
Nothing on the 05 car. We may be getting a new 05 convert for SEMA and we will do some more tests then with it.

 

Do you all have this gap? Did I do something wrong? Can I adjust it to close the gap?

 

You forgot to install the weather strip that came with the package.

It's a horizontal mounting one unlike the one that's on the car. :smile:
Mine's completely enclosed.

 

I bought it used and it doesn't come with that weather strip thing. Do they have it at Autozone?

 

You can just use the self adhesive weather strips autozone sells and
just do 2 layers to get the approximate thickness. No biggie. :smile:

 

ALTA2 - When will the Alta be CARB approved for us California drivers?

Yes, as my signature information states, I already have the Alta
installed - and love it.
