K&N 33-2955 Air Filter Product Reviews

Sunday, January 21, 2018 - Part 33-2955
Own a 2017 Fiesta Sedan S, 5 speed, new, not much horsepower noticed, but as supposed to the stock air filter which is very restrictive, the most noticeable difference is at 70mph when the stock air filter the car was at 4,000 rpm and with the K&N filter the rpm's was at 3500, gas mileage is slightly better. This car should have had a 6 speed manual, it fights to move anything over 70mph, so at this speed any lowering of the rpm's is helpful. I could have gotten a cold air intake but with only about 2-3 gain in hp, didn't see it useful except for the sound. This car is definitely an eco box but wish there was more legitimate parts for more horsepower. Having little to no budget to purchase a car, this car for the price is worth a commuter car. Hopefully in the 2018 they will make a 6 speed manual.

Such a small but great upgrade to your engine bay if you don't have the money for a induction kit, or just simply looking for a cheap upgrade get yourself one of these. Makes a little more noise from the engine bay & it helps it in the long run. Throw your old boring paper air filter out and get yourself a K&N Replacement Air Filter.

Filter is great. Installed on 2014 Fiesta ST in stock air box. Throttle response is faster, noise is barely changed. Service was awesome - quick dispatch + delivery tracking.

I am french so I will do my best. I have K&N in my two cars ( Ranger and Fiesta ) to begin by the air filters. They are wonderful, you feel more power above 3000 RPM and a better pick up. But the big thing is the idle is so smooth. The power is more linear and available when you need it. Lets talk about the gold oil filter, I simply love them. The nut on top is wonderful and the filtration seems to be perfect and the filter is solid. K&N are a step above others and nothing else will go in my cars. Almost forgot! Shipping is so fast its like if Superman is the delevery boy! :)

Easy to fit. More performance but too early to judge improvement in economy.
