K&NEngine Air Filter: High Performance, Premium, Washable, Replacement Filter: Compatible with 2013-2018 Nissan Altima L4 2.5L, 33-2478

Siempre he comprado filtros K&N para todos mis carros y motocicletas. Muchas personas consideran que no funcionan y que daña los motores y los sensores de flujo de aire, yo nunca he tenido un problema y me olvido de andar cambiando filtros desechables, con este me quito de preocupaciones por 50K kilómetros antes de lavarlo tomando en cuenta que no vivo en un lugar con mucho polvo, solo en la ciudad.

باختصار تجربتي مع الفلترالصرفية تحسنت -عزم الموتر قوى واختلف عن فلتر الوكاله مع انه نظيف وجديد لكن الموتر مكتوم عكس كي ان يوم ركبته خف الموتر -الموتر خف بشكل عام قبل لازم ارفع ار بي ام شوي عشان التسارع بشكل اكبر لكن بعد ماركبت الفلتر صرت ماعدي ربع الدعسه -استجابة الدعسه صارت اسرع واسلس -صوت المكينه اثناء التسارع خف شوي -

This filter fit my Altima as advertised - just drop it in and youʻre done. I canʻt say it increased horsepower but I did see a bump in mpgs by about 1 additional mile per gallon. Itʻs not much but I think the filter lives up to the K&N claims. Iʻll plan to cleaning the filter every 12 mos or so but for now Iʻm just enjoying the smooth acceleration and additional mileage gain.

The unit was pre-oiled and ready to go for immediate use out of the box.Although the filter is sealed in a clear plastic bag, I noted the outside of the box it came in had some obvious oil spots on the outside that had somehow bleed through the plastic bag. Replacement is as simple as un-snapping five air cover retainer straps (for my model of vehicle) removing the old filter, and just placing the K&N into the same place. I did use a paper towel to wipe off oil from around the frame prior to inserting.The filter comes with a stick on decal that you mount to the top of the air filter enclosure so any others who are looking under your hood and may possibly have reason to check the air filter know it is a K&N and that it is not a disposable filter - meaning leave it alone and do not take out and throw away. Nice touch, I highly suggest putting it in place.My vehicle is just over 14 months old, 10,450 miles on it...not many miles for the length of time but it is those short drives that take more toil on parts and filters, I live in a metropolitan area where air quality is not spring fresh and the original filter showed this as it was quite dirty. After installation I started the vehicle up and noted the RPM was a bit lower at idle @100-150 or so. A quick spin around the local oval and straightaway was peppy and responsive, more so than before...clean filter, better air flow? You bet as the filter was the only change out I did.Highly recommended, and fortunately as it is a K&N I will never have to purchase another one - just keep this one cleaned and oiled as necessary.4-12-2014 Update: So far I am seeing a 1.3 mpg increase with the K&N filter in place.
