So I've had this on for a few days now and absolutely love it. The exterior fit is great and perfectly conforms to the lines of the hood. However you should go into the install prepared as there are some challenges that come up during the install.
Firstly the hardware, if you've read the other review on this you will know that they got pretty lacking hardware to install this with and they are correct but, it seems they upgraded the hardware. as my hood scoop actually came with a full set of 5 bolts and did not include the pop clips, however my first scoop came cracked and needed to be replaced. That was on UPS and not of the part itself as that box took a beating during the shipping. The replacement came with the plastic clips instead of bolts, now thankfully I had saved the bolts from the first kit and I was able to use those instead. If you receive the plastic clips below is the list of needed hardware to go full bolts. There's also a reference image with the good hardware for comparison
4x M6 or 1/4-20 Bolts, You want a length of between 16-20mm. The one shorter bolt that both sets of Hardware comes with is an M6 bolt and since the OEM bolts are metric I'd personally go with the M6 bolts for the sake of standardization
4x Standard Washers
4x Hex Jam/Low Profile Nut as you will want these 4 nuts to be thinner than standard nuts
4x Low Profile Thumb Nuts, you will want the style that are a flat disc that's threaded all the way through and don't have any kind of stand-off. Also make sure to get something with an outer diameter of 17mm at the minimum. I would recommend something closer to 20mm
Alternatively can use another washer and another nut. Just need to get washers with a outer diameter of at least 17mm
Last thing on the hardware, Both hardware sets have a shorter bolt that comes with a washer and lock nut, due to where the bolts install, its really hard to get a tight enough grip on the head of the bolt let alone an actual tool to hold the head properly and I wasn't able to put enough pressure on the lock nut to thread it on, you may have better luck than I did but you may want to get an extra regular nut in case you aren't able to get it on.
The other problem you will likely install is the alignment of the mounting bracket on the scoop that has the holes for the bolts. down to the slot in the hood for the OEM scoop. During my test fitting before removing the adhesive backing and doing it for real I discovered that the alignment of the bracket was somewhat off and if I had the bolts just slotted in without the nuts holding it tight I wasn't able to get a proper visual alignment on the hood and I wasn't able to position it so that it extends all the way to the back the hood and there was about a 1mm strip of the hood at the back. While it wasn't good as is, the alignment wasn't terrible and while it was in the correct visual position the holes in the bracket where only about 20% off so most of each individual hole was clear. While not ideal this is a issue that is still workable with out too much of a problem if you have the tools. I started by getting the scoop attached in the correct visual orientation using the adhesive tape. Once strapped down I used a dremel with a small roughing bit (wear a mask, gloves and safety glasses) and roughed out the holes to proper clearance for that alignment of the hood. After clearing the holes, before installing the bolts you want to install the insert piece between the 2 layers of metal in the hood that the hood bolt holes run through, see attached photo for correct orientation. Then put the bolts through the holes, the shorter one goes in the center hole, then install the washer and jam nut. Re-install the OEM shroud and then Install the thumb nuts to secure the shroud fully to wrap up.
Last note, I did not have to put extra holes in my hood at the back as the other reviewer did, they had some sort of issue with either air getting under the back portion or the adhesive was bad which resulted in the back portion popping up mid drive, so make sure you follow best practices on prepping the surface and application.
There are design concerns I do have with this long term, mainly the not utilizing the back set of holes in the scoop slot in the hood, and my other one is dirt, debris as well as air getting underneath the rear portion as I think may have happened to the other reviewer as there isn't a full seal down onto the duct in the OEM shroud and while most of the air should flow down into the duct onto the intercooler, there are definitely some gaps (Pic of gap included) that are out of the direct air flow and off to the side and aren't in the direct path of air flow and its something I am a bit concerned about in the long run as some amount of air and dirt will probably get in, and is something I plan on working on a fix for in the future.
But overall I'm very happy with this scoop and the looks despite the challenges and my...
