Dinan Performance Intercooler for BMW | E9X | N54/N55 (NLA)When modifying the car and increasing boost, installing an upgraded intercooler is essential to keep the engine computer from restraining boost as temperatures climb.

When modifying the car and increasing boost, installing an upgraded intercooler is essential to keep the engine computer from restraining boost as temperatures climb. The stock air-air intercooler is quickly overcome with heat and can't keep the intake air cool enough. If it's too hot the engine computer will reduce power to safer levels. A Dinan intercooler is much larger than stock, providing more surface area for cooling air to pass through. Even heat soak at low speeds is reduced, making this a worthwhile addition even for stock or mildly tuned engines. The E9X 335i Dinan intercooler is 93% larger than stock but is a direct replacement with only minor trimming of plastic under trays required for installation. The factory charge piping in and out of the intercooler is re-used.

Note 1: E92/E93 335is - Does not fit vehicles equipped w/ Active Cruise Control.
Note 2: E90 335i - Does not fit vehicles with ACC. For use with both Standard or M-Tech Bumper.
Note 3: E92/E93 335i - Standard Bumper. Does not fit vehicles with ACC.

This is a necessity for anyone that tries a car!!
Size: 20oz 6pk
I haven’t used this yet, but I bought a case to give to my family members. My friend who came outside to a flat tire. It was a Sunday in Utah so there was really no one that could fix it. Walmart told her to get this product. She had to drive home immediately following using this product (300 miles) It has been over two months now and my niece is still driving on that tire. It was a brand new tire that was costly so she decided to just wait and see how long this product will work. Great gift for anyone in the family that drives. This does not work on a blown tire. If you wake up in the morning and your tire is flat, or you get out of class and your tire is flat, just use this product and no calls need to be made.

👌 Kaboom! 🌹 Air fills the room! 💥 Inside your tyres, that is ✨💖

Right out of the box this little wonder inflated my motorcycle tires to the decimal. I set it to .5 over on the digital pressure gauge so the pulling out doesn’t lower the PSI. This machine worked easily, flawlessly, and if you’re on the fence, I’d say pull the trigger. The hoses on mine screwed together making it just about the right length. Dunno how long it lasts but - wow - not much bigger than an old transistor radio & was controlled intuitively. Easy port on bicycle, cycle, auto. It’s a wow & I’m hard to please.

Impressive for its size
Color: Yellow, Number of Items: 1
Great for keeping handy for bikes and even some use on the car tires. Pumped all 4 golfcart tires up from 10 to 22 psi. I am pleased with this purchase and keep it in our Jeep at all times. Works great and is compact. Easy to use. Do read the directions about maximum continuous run time and required cooling off period. Recommend & I would buy again & expecially as a gift.

Absolute Necessity!
Color: Orange, Number of Items: 1
So, the AstroAI arrived today. It was left in the mailbox because it was raining like crazy at the time. I had to go back & watch the videos again to learn how to use it. I'm like what does this thing at the top on the right hand side do. It allows you to screw in the hose & use it as a handle for carry; interesting considering it's small size. It fits into the palm of your hand. To my surprise, it comes with 2 hose attachments. One that screws onto your tires & the other one that snaps onto your tires. It also comes with the other smaller attachments. It comes charged. I tried it & it works great. Definitely worth the money because you don't want to be left on the side of the road or stranded at work coming out to find your tire has a slow leak, especially after working all day!
