K & N Performance Filter

Price Paid:  $80.00 from Local Auto store

Year / Model Reviewed:
2009 Ford Ranger

Strengths:
Better flow means more air

Weaknesses:
Better flow also means less filtration. Also messy work of cleanning with special detergent and oil (costly too!)

Summary:
Get better MPG, better response but very dirty intake. The filtration rating is really up to the amount of oil coating, more oil better filtration, but less flow.

Strengths:
Better Miles per Gallon
Better RPM running rate (lower - better on the engine)
Re-usable, environmentally friendly

Weaknesses:
Initial cost is the only "weakness" however once you realize the benefits you are receiving, that is an insignificant point.

Summary:
I have just installed a K&N Filter on my new Impala (with a 3.5ltr V6) and it helped significantly. I have had these filters on all of my cars since the very first one I have purchased and they are amazing. I have had recommendations from many mechanics and auto enthusiasts and everyone seems to agree that K&N did very well with the filters. I have noticed an increase in the MPG (better!) and the RPMs (lower!) and it helps your vehicle shift better.

Strengths:
Smooth durning at an speed

Weaknesses:
none

Summary:
Since Mazda wanted $22 for the stock Filter, I thought Why not just try the K and N. filter was simple to replace. I'm not sure if it will increase performance or fuel but did notice a smooth responce through all the gear...
