Review on K&N Engine Air Filter: Premium Performance Replacement (Land Cruiser, Tundra, Sequoia, LX 570) by Brad Davis

I installed a throttle position sensor on a 2012 Tundra but at times my truck was still a little sluggish when trying to keep up under acceleration. After installing the K&N filter, this problem was resolved. Now it's gas on demand, this filter was the finishing touch I was looking for. I didn't have it long enough to see a change in gas mileage, but I did notice a definite increase in throttle response. I can see that you might not notice a change in overall horsepower since the Tundra is a bit sluggish straight from the factory. I like the idea of cleaning the filter instead of replacing it, it should save money in the long run.
