034 Motorsports Turbo Inlet Hose

034 Motorsports Turbo Inlet Hose versus OEM Hose

With hot summer temperatures here in Arizona, I noticed my boost to be much lower and the car felt more sluggish overall – I read reviews on the 034 Motorsports Turbo Inlet Pipe from a few other B7 Audi A4 owners and thought I’d give it a whirl – it’s definitely worth the $75! While the differences are subtle at first – a slightly more noticeable spooling sound and possibly spooling a few hundred RPM sooner – the real difference is when the car has been running a while and the engine bay gets super hot – I’ve noticed less of a loss in power after long drives or track days, which is AWESOME and worth the $75 itself. The 2.0 FSI tends to have really bad heatsoak in our cars – you can run the car for just 5 minutes and its already hot enough in there to roast a chicken. Anything to help the engine breathe easier when it gets so hot is worth it in my eyes.

You can see in the picture above that the new product doesn’t have all of the bends and accordian style tubing the OEM inlet pipe does – it’s also silicone which is less prone to collapse and flex in high temperatures than the cheap rubber/plastic compound used by Audi and is a more efficient design. It also looks a lot nicer!

Install was a snap – you only need a screwdriver and some pliers, and it shouldn’t take you more than 30 minutes even for novices. Make sure your engine has cooled down first before attempting to do this, there are a lot of very HOT parts in this area! In the pictures you’ll see my Carbonio Intake but the instructions are the same for an OEM air box as well. As always, attempt this at your own risk and I’m not responsible for any damages or problems, I’m just providing this install guide as a reference only!

First remove the plastic air intake from the grille to the airbox so you can access everything.

Then remove the OEM clamps on either end of the OEM plastic inlet pipe. Be careful not to drop ANYTHING in the piping as that will go directly into your turbo then get shredded up and spewed into your engine!

No pipe at all – don’t drop anything in the hole!

Next grab the new silicone pipe, install one end to the turbo and the other end to the air box and secure the hose clamps – I opted for the hose clamp upgrade and its definitely worth it – the OEM hose clamps are a pain to deal with. You’ll thank yourself when you go to change your air filter out…

This pipe works with the Carbonio airbox just fine, you just have to install the pipe first with the Carbonio loose and out of place – then adjust the Carbonio to tuck under the fender and hood only after you’ve got the silicone inlet pipe fully fastened and tightend on both ends. Once you’ve got the Carbonio fit back into place, just insert your air intake pipe back on and you’re done!

And last but not least, a picture of me really testing this thing out at Inde Motorsports Ranch in Willcox, AZ in about 85 degree heat. It’s an amazing 2.5 mile course with off camber turns, elevation changes, etc. I think the improved inlet pipe helped sustain performance as the engine temperatures grew hotter and hotter and most importantly I had a lot of fun!
