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.
