What is a cold air intake system?

A cold air intake system optimizes air inflow into the car’s engine. This system has shorter and smoother piping to better airflow. The combination with its performance air filter allows the passing of cooler air to the engine. Therefore, the engine will have better combustion, which means additional horsepower and engine efficiency.

What are the 8 reasons to upgrade?

Increased horsepower. Due to the better conductivity of cold air, installing a cold air intake system 21-687P will increase your car’s horsepower by 7.0 HP @ 6500 RPM. That means approximately 217HP on your 2010-2012 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 car would get a better fuel economy. Hence, your 2010-2012 Coupe would have about 2.5 to 5 mpg extra, on top of the original 20 - 29 mpg. Better torque and acceleration. More oxygen means more cylinder pressure, resulting in stronger torque at 5.7 lb-ft. Hence, your 4Cyl 2.0L engine will accelerate faster at a total of 228.7 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 replace it, its part number is 21-2047DK, which has dimensions 7 in (178 mm) x 3.5 in (89 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 aggressive. The cold air intake system has a red non-woven synthetic air filter that is round and immediately visible when you open the hood. It’s the first thing that catches your eyes with its 3.5 in (89 mm) diameter polished intake pipe made of aluminum. Engine sound is enhanced. Yes, the intake will change the sound of your ride. It will sound louder and more fierce, while the air passing through it will make a hissing whistle sound when you push on the throttle. A lot of people online complain that the sound change from performance intakes is overrated. But you can see it for yourself in this video. We at Genesis Tuners are confident that it makes a huge difference. Easy DIY Installation. Swapping out your car's intake with the one from AEM is easy.
