I wouldn't say it's all BS ... You can see pretty good gains on the top end from a high performance intake systems vs. the stock intake system.

You mean like effect gas mileage?

I was thinking more on the lines of having enough power to accelerate to 70mph on the interstate. Also, I dont know how the ECM would react to a 95% level of restriction on the filter. I wondered if it would throw a code if it was at WOT and nothing was happening.

I dont know, there was just some part of me that felt it was wrong to tape up my air filter
