K&N Engine Air Filter: High Performance, Washable, Replacement Filter: Compatible 2010-2019 Hyundai/Kia (i40, Elanta GT, i30, Elantra, ix35, Tucson, Carens, cee d, Forte, Forte 5, Certao, K3) 33-2451 | Fits Select 2010-2019 Hyundai/Kia (i40, Elantra, GT, i30, Tucson, Forte) (See Product Description)

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.

Million mile warranty. Never needs changed for the price of 2 or 3 standard ones. Get the re-oiling solution as well, had difficulty finding it locally near Glasgow, Scotland.

Very good item delivered quickly at a good price.

Fit's perfect does what it says on the box. thanks

Good K&N always used K&N

all as described... fits perfect

Did not fit waste of money

this product doesn’t fit my hyundai i30 2015 model

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!

Me gusta cuidar mi carro y le pongo lo mejor

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

افضل من فلتر الوكالة 👍🏻

De las mejores marcar en accesorios para coches. Es costoso, pero te olvidas de filtros.
