K&N Engine Air Filter: High Performance, Premium, Washable, Replacement Filter: 2010-2019 Hyundai/Kia (I40, Elanta Gt, I30, Elantra, Ix35, Tucson, Carens, Cee D, Forte, Forte 5, Certao, K3), 33-2451

Once I replaced the new original air filter with the KNN filter, the car throttle feels very light and responsive. Very noticeable increase in acceleration. Worth every cent!

I bought this filter for my 2013 Hyundai Elantra GT and it fits perfectly. The 33-2451 filter has the typical premium build that can be expected of a K&N filter, and inside the box they include a warning sticker that reminds anyone under the hood that your vehicle is equipped with a lifetime filter, a warranty card, and a sticker of the K&N logo. I can neither confirm nor deny whether the the K&N logo sticker adds additional horsepower to your vehicle, but I attached it to my Dell laptop, and it seems like I can now type faster. I've been a longtime buyer of K&N filters, installing them on both on road and offroad vehicles. While the initial purchase of a K&N filter is a higher than that of a disposable filter from companies like Purolator or Fram, K&N's ten year, one million mile warranty on their air filters will guarantee that I won't have to worry about buying a new disposable air filter for my car each year and will only need to wash this filter every 50,000 miles or so. Since I hold onto my vehicles for a long time, this filter will prove to be a great value in that field alone, but when you factor in the slight performance and fuel economy increases, it makes buying a K&N cotton washable air filter a no-brainer.

Parfait fait sa fonction je recommande fortement gain de puissance...merci

افضل من فلتر الوكالة 👍🏻

I have bought these style of filters for 3 cars now - a very nippy Audi TT, a Nissan Qashqai and now an elderly i40 estate. Although it obviously doesn't give any noticeable increase in acceleration, it does seem to get me about 5% increase on MPG. What's more noticeable in all the cars is the low end power, the smoothness of the drives and how much less I need to change down a gear when slowing through village roads (I live in a rural area). It's just a *nicer* drive even on the 1.7 diesel with 190k miles (305k km!) on it. Plus not cleaning vs replacing seems slightly better for the environment.
