    Just installed ECS Tuning Intake

    Guest-only advertisement. Register or Log In now!
    Your friendly neighborhood forum modder is here back for another semi-DIY. Got in as one of the first orders for this new intake and figured Id play Guinea Pig for you guys and let you know how it is.

    First thing I have to say is, the box is very pretty lol(see first pic). Its like seeing one if the best packaged Christmas gifts. Presentation well done ECS!

    Upon opening the box(unfortunately no picture), you will find everything really well protected with bubble wrap. Each individual piece is wrapped. Dont forget to look through the box to find the little screws and nuts bag at the bottom. However, this is where I have a big complaint. I dont know if it was because I was the first order and they rushed it, but there were NO instructions in the box. I dont mind this per se because I had already read through the PDF instructions on their site while waiting for the intake to arrive. But this is unacceptable IMHO.

    Moving on, pretty much after the first couple steps of removing the shroud I found the remains of a nice mud wasp nest(second pic). Now, this isnt the first one I found in my car. The first baseball sized nest was found the first time I took apart the intake system(remember that post?). Anyway, Ive pretty much taken everything apart by now so I think thats the last of it(I hope).

    I would like to think Im pretty technical and my abilities are on par with most shop workers. Ive done everything short of disassemble an entire engine and transmission. That being said, I could not for the life of me get the turbo intake tube off for almost a half hour(see third pic). That sucker was a fighter and making me break a sweat. Best thing I could suggest is get a small flathead under there and keep prying it up until it gives.

    After all that it was smooth sailing. The only other piece of advice I would probably give is when installing the vent tube on the 90 degree bend. It was tough to get off in the first place, tougher to get on. Dab a little spit on it(ahh, the natural lubricant) and it will slide over much easier. It will dry without issue.

    Overall it took me about an hour and twenty minutes to install. This included the almost half hour trying to remove that one stupid piece. If you are technically inclined this should be a nice challenge. If you arent, it will be worth challenging your abilities.

    Oh, and the other awesome thing I have discovered about the A4?!? If you drop anything down to the floor, theres tons of room to reach down around the engine to get it. Im saying this from experience from this install.

    And thats it, looks really nice and the materials are top notch. I havent driven it yet or even started it. Ill report back tomorrow with that but I wanted to get this up here now for your viewing pleasure.

    EDIT: Ok, finally took my first drive with it today. I did some slow speed acceleration, WOT acceleration, and some cruising around. On the first part, the slow speed acceleration, you will hear the intake a lot. Actually, this is pretty much the only time you will hear the intake, when driving around town. If the windows are closed and the radio is off, you will hear the car breathing with every tap of the pedal. This is funny because at WOT, you dont hear the intake at all. That is, until you release the pedal and the car sounds like you have a BOV with a big "WOOOSHHH" of air being released. With the windows down you hear it a lot more. People around you can definitely hear it. You can keep goosing the throttle making the turbo kick in and then it shuts and you get the BOV effect. Cruising at a steady pace you wont hear it at all, and depending on how loud you listen to the radio you might not hear it that way either. So, performance wise, I feel like there was definitely a little less lag when starting off the line. Maybe because I heard the car sucking the air in I was focused on that and it gave me the impression the car was moving quicker than it was. Not sure. But when I was on the highway and I mashed the pedal down, the engine definitely sounded more aggressive than normal, not like the weak typical 4cyl I had complained about previously. Anyway, Im happy and with the weather getting crispy out now Im sure my car is more happy too. Ill try to get around to putting up some sound clips if I get enough requests.

    EDIT 2: Heres a quick soundclip https://youtu.be/1w1v2hMT4Z0
    EDIT 3: Heres a second soundclip under load https://youtu.be/FO1x9txKgbA

    Thanks for the order and sharing your feedback!

    Since we have the on line PDF we really don't see any reason to include a paper copy of the install instructions. Plus less paper means more trees, which is better for the environment! :)

    Also a heat gun or hair drier will help loosen up the turbo inlet pipe for those that experience difficulties.

    I understand the philosophy but not everyone has access to a laptop or iPad to bring by the car. Reading it on a phone would have been abysmal. More than likely, people will print the instructions out anyway negating the saving the trees thing. Anyway, dead horse. The heat gun would have probably helped had I thought of it, usually these things just pop off for me.

    Great writeup, thank you for sharing. I dig the extra sounds we can hear in your video clip.

    Sounds really good. Get any kettlepot sounds holding steady at certain RPMs? I know the B8s did this, not my cup of tea (no pun intended) :)

    Not sure what the kettlepot sounds like, I can only imagine though. No, when cruising at a steady RPM you dont hear it at all. You really only hear it mostly when starting from a stop and accelerating moderately. At WOT you dont hear anything until you let go of the pedal.

    I just installed the ECS Tuning intake on my 2017 A4 yesterday. The intake increases the engine sound but does add a significant blow off valve sound while doing so. The system installed in about an hour and half. The turbo tube came right off with a small flathead screwdriver. The look is very clean and all parts are top-notch. I did not notice much of a power bump but last weekend, I installed the APR Stage 1 tune. APR did a great job with this one. If I did not install the APR tune, I am sure I would have noticed a larger power bump in the intake.

    To summarize: The APR tune is a night and day tune. You will notice dramatic power increases. Go for it 100%. The ECS intake is easy to install, looks great, high quality, increases the beefiness of the sound but also makes your car seem like it has a blow off valve. I'm glad I did both but you would never regret the APR Stage 1 ECU tune in my opinion. Great job ECS on the intake!

    Appreciate all the feedback!

    Regarding the blow off valve noise. The stock air box does a very good job of containing this. So when you delete that it open up the intake more so you will definitely hear the diverter valve working.

    A diverter valve is essentially the same as a blow off valve though one major difference. A blow off valve typically vents to the atmosphere. Meaning the air does not get recirculated back into the intake. These vehicles divert the excess pressure back into the intake. If you were to vent it to the atmosphere like a blow off valve you can easily effect how the vehicle runs. This is because the ECU has already adjusted for the incoming air returning in to the intake. Now when you remove that you throw off the air/fuel ratio which would cause a moment of enrichment due to lack of already metered air.

    A diverter valve is an essential piece on turbocharged vehicles as they protect the turbo from compressor surge. Which is a condition when the throttle body plate closes or there's a reduction of boost pressure from shifting and air gets backed up against the compressor wheel because it has no where else to go. This over time can damage the turbo. To resolve this a diverter or blow off valve is placed in the intake line so you can relieve pressure when the throttle body plate closes.

    Yup, thanks for the clarification Jason. That's why kept saying it was a bov "type" sound. I had debated on adding a true bov to the car but with the intake sound doing what it's doing, no need anymore.

    Jason - Thank you for the clarification. I was expecting to hear the diverter valve more with the intake but wasn't expecting to hear it as much as I did. Can't believe how the stock air box controls the diverter valve sound. It is non-existent with the stock air box. Great product though. All parts and materials were A+. I'm happy with my purchase and would recommend it to anyone okay with the "BOV sound effect."

    No problem! I'm glad you guys are enjoying it! It definitely gives the car a sportier feel when you want it and its tame enough to drive every day.

    Great review. The Videos back up everything you've been posting. I ordered my ECS intake last night. Plan on installing it next week when I get my car back from the body shop (got rear ended). Then going to make a trip out to APR hq to get the Stage 1 Tune installed before Turkey Day!

    Any dyno numbers? even if it's low similar to past intakes of any brand. For what it's worth, ECS has great products. Never let me down on any past Vdubs or Audis. These days I pass on mods just for sound kicks.

    Nice video review BTW

    Awesome! Hope you enjoy it as much as I have been. It's definitely liking the colder weather right now.
