Does anyone know what just the AFE Pro Dry drop in filter by itself will give the F in gains of horsepower? They claim a gain of 60% better air flow. But I wonder what that translates to in terms of horsepower.

I don't think I've answered my own question on a forum before, but I finally found pretty conclusive evidence of what just adding the AFE Pro Dry drop in filter by itself will give you in terms of horsepower increase. I finally typed the right phrasing in Google. I found that there were several guys installing these in their trucks. Based on my findings, I would say that the drop in alone will give us about 2 to 3 horsepower at best. But if someone has a dyno on just the drop in alone on an F, that would be great.

I put one in and i can't really feel a difference.

I'm bumping this up. It would actually be very interesting to see the power difference between using this drop-in only, vs. the Takeda intake with the tube and the AFE cone. Any chance of adding this comparison to the intake shootout as a bonus?

My experience with this filter is actually similar to owner feedback from the Takeda. It seems like the torque comes in at a wider rpm range and there is less kick at 4k because the build up is smoother.

Not sure that the actual gains are significant, but I wouldn't draw a conclusion based on comparisons with people dropping these in their trucks. Different cars have different responses to mods.

Good point Primecut. I bet the F does respond differently. I'd love to see this in the intake shootout.
