K&N 33-2451 Replacement Air Filter,Heather Red

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!

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 👍🏻

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