Well looks like I got a project for next weekend. I'm excited to see if my mpg gets better because of this.

 

I BELIEVE! I BELIEVE! This long thread bugged the crap out of me until I did the little mod myself. I took my airbox snorkel off and threw in a K&N drop in filter and I must say...PRAISE THE MPG!

Before the cheap modification enhancement to the air intake suction waste of plastic piece of crap (aka Snorkel), I was getting roughly 28-29 mpg with 10% highway and 90% city. With the same driving style, I am now getting 34-35. I feel like the car is lighter, oh wait it is...the snorkel weighs a few ounces.

Anyway, just thought I'd support this long thread and give y'all my results. Happy and safe driving to all, since speeding is out of the question with our enormous powerplant!

Well, after my first full tank, I'm running about 33.7mpg (up 2 from before the mod). So it's not overwhelmingly great but it's still fun. I have yet to add the K&N filter so hopefully that will help even more.

 

Welcome to the fold, young Paduwan!

But seriously - congrats, guys - glad its working for you, too!

 

Hmmmmmm....I purchased the YDR CAI on here awhile back but never got around to installing it because I had to remove the strut bar and cruise control to remove the "air box". Now I'm wondering if I should just remove the snorkel and sell the CAI?

 

This mod truly works. I was struggling to get 33 mpg (filling up at 10 - 10.5 gallons) while driving 65mph. Most of my driving is hwy miles; about 27 miles each way. I took off the useless snorkel and filled up. I drove the same way I have been and filled up finally and got 36.2 mpg ( filling up at 9.8 gallons). I could have easliy gotten another 30 miles out of my take. I also have a K&N drop filter. So anyone that says that this doesn't work is full of crap.

 

Are there any differing opinions on this mod out there? I'm wondering if I have missed any of the downsides?

 

Put it back on and see if your mileage goes back down.

 

 

Ok, it's spring time now and I get some hwy mile from april to september. First hwy trip since the snorkel mod and I've seen good results. My best MPG for this particular 48 mile section of hwy was previously 36mpg at average of 55mpg. Today I was able to get 40 on that same exact trip. Of course there are other variables but I take this drive probably 20 times a year and like I said the best I ever got before was 4 mpg less. So somethings working, part of it I'm sure is some improvement in technique too. On the way home I found the "old" highway which is now kind of a detour. So it added some more miles to the trip home but it has less traffic so I didn't have to speed up to 65 as often for part of the trip. On the way home I got 47mpg for the 52miles so I drove more miles but used less overall fuel and got home only a few minutes later.
I am now convinced.

 

WOW you must be getting better gas then us in the lower 49 states to be getting 47 at highway speeds. I usually only get that high driving around 30-40mph and I have some better lubes in my engine and tranny and it is a manual. Of course each time you have to stop at that high mileage will really kill it - like you can loose 1mpg for each 35mph stop. I get hit all the time coming back into town so I have a limit to what I can get.

 

Ok, another newbie here to bug you with questions I read 80% of this thread and haven't seen a single tC owner chime in, so I figure why not be the one to ask if this works for us, too... Again, I am a n00b, and having just read through this, I'm anxious to dive under the hood and remove the snorkel - if indeed the tC has one hahaha

Any thoughts/experiences on this?

 

That trip had no stops on the freeway. But there was about 8miles of the trip that were in town. There are gentle hills on that stretch of freeway and I was getting about 30mpg on the way up hills and 65+ on the way down the hills. Just tried to maintain good mpg on the way up while maintaining decent momentum and then just feathering the throttle on the way down to gain some momentum and coasting in nuetral if it was a very long hill. I don't know about the better gas up here but I'll see if I can do it again next time I go on the same trip. I'm sure if I did the 65mpg limit it would drastically drop down to 35mpg or less.

 

If the increased airflow offered by this mod results in better mileage, why wouldn't the same results be reported by short ram intake users? Or are they?

 

Ahhh AKXB that sounds like a pulse and glide which will net some great mileage if you can pop it in neutral on the glide.

 

Thats a great question, Soooooo.....sri guys do you get better mileage?

 

Ok, since everyone's jumping to reply, here's pictures of the inside of the tC near the airbox:




I'm thinking that the hose with the big 3 on it is the one that would be removed, as on the other side of the box there's another hose that leads to the engine - am i far off here?

I welcome any thoughts on this, cuz I'd like to try this mod too if it won't kill my car

thanks!

 

changing the air intake period will allow you to use more fuel. more air equals more fuel to be used. that simple. In the case of removing the snorkle, the air flow is being freed up without adding more air to the mix. less restriction really over a shorter distance. the engine is working less hard now to produce power.
I have finally refilled the tank after $27.50 in gas( that's another story thanks to oil mongers) and I have recorded 28.8 this time over the 25 from last time. Now this data for me will inconclusive as I also added air to the tires and my wifes tC also got better than usual gas mileage. She was averaging 24/25 and she did 27! Her car extra stock too. My Daytona is also getting better than usual gas mileage this tank after a 19mpg run, down from the usual 25 as well. That was weird all in itself and I am still scratching my head on that one. I do the same things everyday when I go to and from work in that car or in both of my cars. I had to have gotten a better gas mixture this time. So, I am still watching and studying this in my xB. Back to rain for tomo and I put the car away.

 

I'll try the snorkle removal on the wifes car and see what happens to those that were asking.

 

Thanks - I'm looking forward to the results of this! I've got a K&N filter on the way to help with any issues of dirt/debris that might get inside, but overall I'm hoping this works as it does on the others
