8 Reasons to Upgrade to 2013-2014 Genesis Coupe Cold Air Intake 21-728P

Replace your stock air intakes with 21-728P to improve performance quickly and easily.

What part replacement will have the best performance without breaking the bank? Buying and installing an aftermarket 2013-2014 Genesis Coupe cold air intake is one of the easiest ways to enhance the performance for $358.99. It has more benefits than just an increase in horsepower. In the product description below, you will learn about these benefits in detail. It will cover the following: * What is a cold air intake system? * What are the 8 reasons to upgrade? * Why should you buy 21-728P by AEM Intakes? * What to consider when purchasing?

What is a cold air intake system?

A cold air intake system allows cold air to enter into the engine. The intake pipe is engineered to have less turbulent air flow, decreasing air resistance. Then, it is made shorter with a uninterrupted route to the engine, without muffling devices. Its design and combination of materials used ensures colder air to pass through to the engine.

What are the 8 reasons to upgrade?

Increased horsepower. 21-728P will channel colder air to the engine, which means denser oxygen per volume. More oxygen will result in better internal combustion of the engine, producing higher horsepower of extra 12 HP @ 2800 RPM. That means estimated 290HP on your 2013-2014 Genesis Coupe stock. You can see the dyno test results here

Improved gas mileage. Since cold air intake systems force a balanced air to fuel ratio, your Genesis Coupe would get a better fuel economy. Hence, your 2013-2014 Coupe would have about 2.5 to 6 mpg extra, on top of the standard 21 - 30 mpg.

Better torque and acceleration. More oxygen means more cylinder pressure, resulting in forceful torque at 22.5 lb-ft. Hence, your 4Cyl 2.0L engine will accelerate faster at a total of 297.5 lb-ft of torque.

Reusable filters. Instead of the stock air filters, you can wash, rinse and reuse the non-woven synthetic air filter. If you want to change it, its part number is 21-2047DK, which has dimensions 7 in (178 mm) x 0.938 in (24 mm) x 3.5 in (89 mm) (h x l x w). You can’t keep washing it forever. As a rule of thumb, make sure to replace it every 25,000 miles.

Looks more menacing. The cold air intake system includes a red non-woven synthetic air filter that is round and immediately visible when you open the hood. It’s the first thing that attracts your eyes with its 3.5 in (89 mm) diameter polished intake pipe made of aluminum.

Engine sound is enhanced. By design, OEM air intakes are smaller with angular turns and rivets. It compromises fuel economy to provide a more of a muted ride, meant for comfort. In contrast, with 21-688P aftermarket cold air intake, the natural whooshing noise will be re-established. It compromises a quieter ride to provide performance.

Easy DIY Installation. Swapping out your car's intake with the one from AEM Intakes is easy. You do not need a professional mechanic for it (although we always do recommend it). It takes about 90 mins of your time, and you only need a handful of tools. You can find your instructions here.

Affordable upgrade. Upgrading your 2013-2014 Coupe with a cold air intake is probably the most common part to upgrade. It’s because it doesn’t cost much. You can get the 21-728P with all of the benefits above at $358.99. If you’re in the mainland US, we can generally get it to your door in about 3-5 business days upon shipping.
