K&N 33-2333 Air Filter Product Reviews

Perfect fit replacement to original air filter. Really woke up my LR3's 4.4L V8, specially in the upper RPM. Feels also like there are some more torque at lower end RPM. Engine sounds like much more healthier breath across RPM range. Seeing forward to see if it even improves MPG.

I have been using K&N filters for many years. I like that you don't have to keep replacing them every service. Also they have a better air flow over standard filters.

This is now the 10th filter we have had from K&N for our fleet Land rover Discovery 4 commercial and standard cars, more performance, more fuel economy and we would not hesitate to have another. Thank you K&N. regards, Simon.
