Design Engineering 10396, Inc. Reflect-A-Gold 2" x 15' High-Temperature Reflective, Adhesive-Backed, Insulation Tape/Wrap. Made in America.

This tape seems simple but appears to do a good job of reflecting heat so it doesn’t heat your intake pipe through exposure to hot temperatures in the engine bay. Many years ago, when I was young and less informed, I decided to install a “cold air” intake in my 2002 Expedition because it looked cool, sounded cool and promised additional numbers I quite did not understand. Fast forward almost two decades and now that I really appreciate my cars, I was left hoping I had not throw away the original intake assembly. Having thought of installing a closed-box intake to reduce exposure to hot air, I decided to first try these type of products before spending a couple of hundreds in another kit. As far as testing, I ran the car without the tape in the early morning, with a Miami temperature of 89 F, while taking my kid to school, and noticed that within 15 minutes of driving, the temperature spread between the intake and the ambient temperature was between 30-40 degrees (89F ambient, 119-130 IAT) at idle. While cruising at 35-45mph, the temperature difference was between 9-15 degrees, which is not bad. Once I taped the intake, I idled the car for about 20 minutes and noticed that the temperature spread was not more than 5 degrees more or less (87 ambient, 90-92 IAT). Obviously this is not an apple to apple test, yet, since the engine is bound to get hotter during periods of acceleration and idling while routine driving, so I am looking forward to testing it tomorrow in our morning drive to school, at the same time, same route, same speeds and likely similar ambient temperature Installing was easy but patience is key. I did, however, not have enough to fully wrap the pipe components with this 15’ roll, and am weary about spending another $30 for another roll unless I see true benefits. I did see other much cheaper rolls listed here, but probably are just gimmicks so didn’t want to waste my time as this brand was recommended by multiple online reviews. In theory, it seems like a sure way to care for your engine by providing it fresh ambient like air temperatures, which translate into better performance and likely less strain, more so for an older engine like this. And seeing how I like to drive my 2002 Expedition more than my 2025 Suburban, I want this thing to last as long as I can get it to!

Absolutely gorgeous, definitely keeps my intake temps down. As per the heed of other peoples reviews around the internet with premature peeling of the tape, I first sprayed the item I was wrapping with 3M super 77 spray adhesive. In my case I wrapped a turbo inlet I built as it is located across my turbos hot side. Before wrapping the intake, my first few drives with the car showed heat soak after full strong pulls, especially when it is hotter outside. I installed the tape by measuring the diameter (3" in my case) and added roughly 1/8" just for complete coverage. It took a while, but I flipped every strip over and also sprayed the 3M adhesive to the back side. After a few hrs of operation, one with higher engine temps the tape performed as expected, was cool to the touch shortly after shutting down the vehicle and showed zero signs of sagging or peeling up. A few drives and days later and same results. Even sprayed it off with water to clean the road debris off. One last thing worth mentioning, any sort of radius is going to be difficult to wrap. For this I cut the wrap in half and used shorter 1.5"-2" strips to get 180 degrees of coverage properly. If you are wrapping an intake or intercooler piping and your filter or coupler is rated for same diameter, I recommend leaving the gold tape back just enough for your filter to clamp on. In my case I am running a K&N 3" cone and it was too snug to fit over the gold wrap. After a few frustrating attempts I eventually ended up scrapping one 3" section as it had gotten too beat up during attempts to install my filter to consider presentable. See attached picture of my engine for reference.

Very good stuff. I use it to protect my CBR1000RR's farings from the Design Engineering heat wrap and Akrapovic full system. Better than OEM heat tape.

Worked as intended, 2”x15’ was just enough for my cold air intake. Easy to work with. We’ll see over time hold up.

Fantastic! Very good quality tape. Adhesive is tacky but forgiving. Application is good, the foil doesn't crease much if the tape starts to bunch up. I've used this on my CF intake to protect it from my alternator as well as on my fiber board night stand that's right up against my heat register. Works a charm.

I went a little nuts and decided to tape my entire aluminum firewall and footboxes with this stuff to avoid the bare aluminum look on a 1965 cobra roadster build. I think it's going to look solid when its all said and done, and hopefully it keeps my feet from melting under the heat of a supercharged Coyote. Wipe everything with isopropyl alcohol first and it sticks wonderfully. My only thought is that the sheet version of this is NOT the way to go. It comes all folded up awkwardly and has creases in it right out of the gate, and no amount of technique can get them out. The tape on the other hand is awesome and goes on super smooth. In my photos you can see the difference between the taped portion and the single sheet portion. Stay away!

Cuts well, sticks on cold air intake piping well. Reflects heat extremely well. After a long drive I can grab the cold air intake pipe and it’s warm but not burning hot to the touch like it usually is.

I tried using a cheaper version of this product on the airbox in my car that peeled off a day later. I decided to try this stuff next hoping it would do better and I was not disappointed. Several months later it’s still sticking. I should’ve gone with DEI to begin with, always had good luck with their other products.

Very easy to install. Stick nicely on my silicone intake. Buy it without hesitation.

They know what they’re doing! Temps changed drastically vs leading competitors

works as intended.. really hard to do on a bend

Quality item as you can expect!
