When I installed the filter my avg mpg went up 2mpg from 26 to 28. I am relieved that the map sensor won't be getting oil on it from the filter.

excellent fit with AEM dryflow filter. it comes in different sizes so make sure you get the right one for your filter. I keep getting CEL from water getting to the MAF sensor with my intake after a car wash or a good downpour. installed these and problem went away. also made my filter cleaner for longer clean intervals.
