I did a dyno test on my R. Drop in filter gave about 1.5 hp. AEM/Icebox/Iceman all gave 3-4 hp. Figure the $/hp is in the filters favor (I only paid $30 for my K&N). I have an Icebox and would recommend it to anyone but just some info to think on.

 

Wow, who would have ever figured, 1.5whp from a filter, hmmm...that is some good food for thought.

Trey, do you think that could maybe be chalked up to margin of error on the dyno? You know as well as I do that everything from weather conditions, type of dyno used, temperature, etc., affect dyno results.

Not doubting ya, though, I just like the discussions :P

 

Anything is possible. This was an average of 3 runs with the filter. It was on the same day. I tested the AEM, Iceman (Which made more than the AEM BTW) and the Filter.

I also tested the stock airbox with the lower resonator portion off and we showed an average loss of 3 whp on one car and did the test later on an R with an Avg hp loss of 5.5 hp.

So it is possible but we typically do 3 runs and avg them for claims of gain or loss.
