Review on 🔍 K&N Engine Air Filter: High Performance, Washable Replacement Filter: Compatible with 1981-2019 Nissan/Infiniti/Renault (Maxima, Murano, Pathfinder, Altima, Elgrand, Quest, X-Trail, QX60) - Model 33-2031-2 by Daniel Aboubakar

I have a 2001 Nissan X Terra with a V6 automatic engine. Before installing K&N and Standard Oil. I just took it with me on a trip. The best MPG was 15 MPG Highway. I just drove at 75 mph and got 16.5 mpg. So it really did improve gas mileage as it was claimed. Not much, but with a travel of over 600 miles and 2.50 per gallon. The saving is $9.10. only on this trip. Not a lot, but considering the average driver drives 15,000 miles a year. This will save you over $227.00 in gas. Certainly a good investment.
