K&N Typhoon Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 69-5321TS

I bought this about a year ago and it has been one of the best purchases I've made for my vehicle

I put this in my optima back in 2019 and I've taken it out a few times sense and I must say I can feel the difference I. My vehicle performance and gas mileage on and off the highway. It's worth the money and easy to install and easy to clean. I say purchase it if you have the funds to do so it'll improve your vehicle.

5 Star Review

I love this product. Give my car a nice growl and definitely helped with performance. The kit was made very well no problems. One complaint would be the large tube adapter. The tube's are for the smaller tube for the oem part. If they could just give that larger tube adapter I would have given this product 5 other than that solid product.

Not that impressed with this kit. Both connections for the male pipe to barb fittings were not cleaned after applying the glitter paint so the fitting would not thread until I cleaned them. The heat shield is thin and the mounting was bent. One of hoses from the car is larger the the other. The hoses, barb unions, and male pipe to barb adaptors from the kit are all sized the same as the smaller tube. There no parts for connecting the larger tube from the car to the small barbs with the kit so it separates easily. The heat shield also doesn’t support the original fresh air intake duct so there is a gap and the duct is unsupported on the filter side. Whole duct can moved up and down an inch or so versus being secure in the factory housing. It’s all entirely too cheap and under engineered for the price.
