Overview:

Take the performance of your vehicle to the next level with the addition of Flowmaster's Delta Force Performance Air Intake system for 2018-2023 Ford Mustang GT with the 5.0-liter engine. Dyno gains of 21 hp and 23 lb-ft over stock at the rear wheels. The Delta Force system contains an ultra-trick looking, custom molded black Cross-Linked Polyethylene (XLPE) high-flow intake tube, black anodized aluminum fittings, high quality reinforced silicone couplers and all stainless steel hardware for long life and a custom look. Other features include a large diameter high-flow conical shaped 8-layer cotton gauze air filter, which traps more dirt than typical 6-layer designs, a custom-fit black powder-coated air dam with attachment brackets to securely mount the system in place along with soft bumpers to eliminate any metal to metal contact under the hood.

    Excellent Sound Deadening Material!
    Style: 10 SqFt, Style: 10 SqFt
    I installed Kilmat Sound Deadening in my truck, and I’m extremely impressed with the results. The material is thick, pliable, and easy to cut to fit doors, floor panels. It sticks very well to metal surfaces and doesn’t peel, even after heating it slightly to make it more flexible. After installation, I immediately noticed a reduction in road noise and vibrations. Worth the money!!

    A Must Have For Car Restorations!
    Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
    I have been installing this matting in my 74 Datsun 260Z restore and very pleased with the ease of application and overall quality. My car has bedliner coating inside and this stuff sticks extremely well and is easy to trim and shape as well. I have just started installing it and using the rollers to work it in place but I can already tell a difference with just the little bit I have added....has reduced the resonance in the metal already. It's not a fast process but know it will be very rewarding once complete.

    Great sound mat for the price!
    Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
    This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

    Excellent sound deadening mats
    Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
    Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.
