    • Great replacement for MB W212 M157 air intake tubes
If you have a W212 E class with a M157 engine, you've no doubt stared in disbelief that MB has put flimsy fabric tubes under the hood, now torn in a bunch of places thanks to the simple act of trying to get your oil filter out. Well, I'm happy to say that this plastic tube and couplers are pretty much a prefect fit to the OEM plastic connector pieces and a great replacement. Not only is this a fraction of the price of an OEM replacement that will probably rip in another couple years or so, it looks 1000x better. As others have noted, due to the terrible packaging, one of the couplers will arrive squashed and deformed. No worries, either pop it in a 300 degree oven for a few minutes, or run your heat gun over it for a bit and it will not only pop back to a circular shape, but also become pliable enough to slide over the OEM plastic coupler pieces. As it cools, it'll mold nicely to the plastic. It was such a tight fit that I didn't even bother gluing it down or clamping it. I think I spent more time and effort tearing out the old fabric tube off of the OEM connectors than actually molding and putting the new coupler and tubes on it. You'll need one set for each side, although I only used about half of the length of tubing. I've seen pictures of what others have done and it looks great, but I hesitated for a while before buying this, wondering if I could replicate similar results since I don't have bodywork experience or tuning experience or anything of that caliber. But really, all you need is an oven (or heat gun), some needle nose pliers to help remove the old fabric tubing pieces off of the plastic couplers, and scissors and in about 30 minutes, you'll have replaced your torn fabric tubes with these plastic parts that look factory. One big worry was how it would perform in a hot engine bay... wondering if the plastic duct would melt, deform, come apart, or somehow jam up the air intake. I've now had this in my car for about 6 months with combination of boring daily commutes and the occasional spirited driving, and haven't noticed any performance deterioration, even under wide open throttle with that tubocharged V8 sucking in air like crazy. Car performs and drives like before. Of course, not surprisingly, haven't noticed any performance improvement either. ... show more

    • Perfect adjustable ram air tube
This works great for a DIY ram air on E90 325/328/330s. Can be a little bit of a tight fit with xenon afs headlights. Does help performance a little bit at highway speeds. Would not recommend this to be routed to the lower bumper fo anyone who lives in an area where flooding can occur

    • Good product. Poor packaging and kinked coupler.
Review Image by me 4 Real me 4 Real

Used to replace the air hose on a 1995Mercedes C230. The good is it’s sturdy. It does the job but it is far harder than it should have been. The bad, the hoses couplers are made of a very hard rubber that’s not very pliable and and one end is packaged very poorly. It is rolled up and crammed inside the hose so when you open the package one coupler has a very very bad kink in it that doesn’t come out under normal circumstances. Thus our the package it is not round and does not fit the included hose. To make it fit I had to boil a pot of water and dip the coupler in and out to soften it up and try and get the crease out and back to round. It did work. I also had to grease the inside with a little Vaseline to get it to go on the hose. This is entirely the fault of the silly way this is packaged. There are TWO couplers and only one is crammed and kinked. The other one is fine. ... show more

    • Spectre Performance 8741 Black 3" Air Duct Hose, Perfect for Cold Air Intake
Last winter I had an ASE shop rebuild my 2.3 Lt. engine for my 1986 Ranger- 3 months later every ring was broke, I got into it myself, ported and polished the intake and head added a few nice extras. With 200 lbs cranking pressure I wanted the little beast to "Breathe!" This section of High Quality Duct gives the Helix Mixer Throttle plate and High Performance Header the cold air intake ,and it does the job very well,and aids in my 30+ Mpg and 120 HP(11 to 1 CR)- , all the needed parts are clamps . I live 90 miles from town and it's a joy to drive this little beast to town for my once a month shopping- Thanks Again Amazon for the Best parts for any of my trucks and other ranch equipment ... show more

    • Don't expect to work without modification and additional parts
It will work well for my intake. The tube though is not really sturdy. And they should include a 3" tube as a joiner to attach to cone filter. You can't use the end to attach it. It will leak and isn't sturdy enough to clamp and outside diameter is too big for that. Another big issue is that they shove the rubber boots inside the tube in the package. This makes them malformed. I had to reshape them with a metal 3" tube and a heat gun. And they are going to leak unless I glue the ends on tube with high temp silicone or maybe E6000. Of course there are no instructions to explain any of this. So I bet a ton of people that bought this just have leaky intakes. So, just know you need to purchase glue, heat gun or hair dryer, and a little bit of innovation skill to actually make this work. If they were open about all this, I would give 5 stars. But since they sell you the product like this to the general public I'm only giving it 3 stars. ... show more

    • Durable and has held up to the heat.
I have a '84 hot rod Corvette that I removed the A/C Evaporator and blower fan from the engine bay. I made some sheet metal plates to cover the fan opening and the evap opening and used this air duct hose along with the 3" duct flanges that Spectre also sells to keep the radiator core in place and keep vented heat working. I no longer have a blower fan but for forced air but I can vent heat when the car is moving and it works great! The duct is about 1.5-2" from a header pipe. I was worried it might melt, but so far it has held up great. ... show more
