I tested some enlarged filters to increase flow while extending cleaning interval. Also note how I enlarged the air inlets to further minimize available airflow. All the details are contained within my thread: https://www.corvetteforum.com/forums...s-arrived.html

Rather than jack your other thread up, I'll ask here @Kracka. I can see the physical difference in the size of the filters. I mean, it is pretty darn obvious. But did it make a difference? It looks like you ran the blue oiled filters for awhile and then switched to the dry grey oversized filters shortly after. I saw your post that FI likes the blue oiled filters and NA likes the dry grey filters. I guess the questions are:

1. Was there a noticeable difference between the 5R blue oiled filters that came with the kit and the oversized Pro Dry S dry filters? Can you elaborate if there was?
2. Are you curious if the oversized 5R blue oiled filter would have similar or different results than the oversized Pro Dry S dry filter?

I'm also curious if the 5R will outshine the Pro Dry S if you have different NA modifications like intake manifold (ported or aftermarket), ported throttle body, and ported cylinder heads for example that will take advantage of the higher flow rate.

@Performance nut sorry for the delayed, response.

Seat of the pants, yes, the larger filters seemed to yield slightly stronger top-end pull while audibly there was an increase in induction sound. I'm sure enlarged 5R filters would have performed similarly, but all independent dyno testing does point towards the ProDryS out-performing the 5R on N/A engines. I tested both types on my C7, as well. I do like the ease of cleaning the dry filters! Shake & vacuum them out occasionally, then when they get really dirty just soak in a warm water bucket with dishsoap, rinse, and air dry. I have nothing against oiled filters though and do run them on both my Jeeps if that's your preference (I may switch one over to dry next time it's due for cleaning just for simplicity).

Ported heads/cam may be another story, but I do have full bolt-on supporting mods on my car (throttle body, intake manifold, headers, cats, & exhaust).

Thanks for responding! A follow up question is I may. Did you put the oversized filter on before or after all your modifications? I can't tell from the other thread other than the Corsa cats coming around the same time.

Kracka

Intake came before the cats, but the oversized filters came after the cats before the Borla. Everything else was done beforehand.

Is there a separate part number for the oversized filters ? Or are the oversized the ones that will come with dry kit ?

Kracka

They are a separate part number that I have listed in my aFe intake thread. I'll go find it...

Hey kracka,thx for all your help with things!
Im deciding on route to go and curious why afe wouldn’t give us the larger filters WITH air box instead on the less restrictive ones?

Kracka

According to my discussion with them, their engineers determined the standard filter size to be good enough and provide adequate gains in airflow. I also suspect they wanted to maintain a single size air filter across all their C8 intake offerings; I do not believe my oversized filters would fit inside their box with the carbon fiber cover.

@Kracka nowadays Corsa has a carbon fiber window to show off your carbon intake!!
