Spicers study is great but it's almost 6 years old and shows only the filtering element itself...Which isn't bad, but not new either.
Show me a test that prove the Dinan intake and Lingenfelter intakes on my vehicles are a scam (especially when coupled with ECU upgrades) and i'll acquiesce and confirm we're completely on the same page

I wanted to start a pool of people willing to pony up $$$ to run another ISO 5011 set of tests. It is a few hundred per filter... just not enough interest.
I'd agree that the properly engineered intake systems (ie the $2500 Dinan cold air intake for the E39M5 for example) do not result in lower power. Indeed the Dinan system adds 5, 6HP I believe (just by memory).
I wonder where their elements fall on the ISO tests.... and I guess I agree that $400 per HP gained is not a 'scam' since you know what you get.
