I'm too lazy to search on the M5Board, but I do know that they put the BMC and the K&N side by side. The BMC had MUCH MUCH more surface area, while the K&N used a lot of rubber where filter should be. On the Dyno, BMC's alone don't do much. However, with scoops and max surface area, plus a more breathable element than stock, I would go with BMC>K&N>Stock.

AFE drop-ins? If they are even equal to the BMC's, I would still get the BMC's. It's like me going to a restaurant and ordering their Fried Rice and found a big fat roach in it as well as getting food poisoning. Not only did they NOT apologize, but made me pay the bill. I certainly wouldn't go back and try their Chow Mein, hoping that the roaches didn't get in there and that it was stored away from the rats, unlike the Fried Rice.

 

What as analogy.

 

I took out my AFE air filter from my E63 and replaced with BMC filter. Showed a gain of 5rwhp on Dyno Dynamics. I'll post my dyno chart later. Need to get from RPI.

 

sorry Im late guys but I guess the questions were answered. cant wait until I have to replace that air filter myself

 

Why would you wait Nerwyll. Change it now.

 

oh, alright. we have them in stock anyway

 

Let me introduce myself. I am the Director of Customer Service at aFe. My email has already been posted on this thread. Just in case it is buried in this lengthy thread, it is paulhardley@afepower.com.

We do not ?lie? about our performance data nor do we manipulate our data to achieve better sales. We are very careful to get repeatable results obtained on our in-house Mustang dyno. I'd be more than happy to explain how we test and why to those who communicate directly with me. aFe stands behind our products 100% and, except for those here, our customers have been very pleased with our products. However, we realize we cannot please everyone all the time. If a customer is not satisfied with one of our products for whatever reason, we will work with our dealers and distributors to get the customer a refund if he desires to return it.

As Director of Customer Service, I will be the person authorizing returns and any refunds. Therefore, I would like to explain our return policies. Please contact the dealer or distributor from whom you purchased the product and request a ?Return Goods Authorization (RGA)?. The dealer or distributor in turn will contact us for an RGA number. When returning the product to us, place the RGA number on the outside of the box to identify it it as a return.

Upon receipt of the product, aFe will issue a credit memo to the dealer or distributor for the price that aFe received. The dealer or distributor is then responsible for refunding the purchase price that the customer paid. This is necessary as aFe does not guarantee the mark-ups and is not responsible for refunding the ?profit? the dealer or distributor made when he sells our products. If you bought your intake system directly from us, please contact me directly to request an RGA and on receipt of the system, we will refund the full amount you paid to your credit card.

Each of you are welcome to email me your questions or comments. PM through this forum may not be the best way to communicate as I do not frequent this forum. I will respond to your comments individually. But neither I nor ?afeengineer? will be commenting any further here because, as a manufacturer, we have learned that any comments we make will be treated with skepticism and derision. I'm sure my emailed responses will find its way here regardless. I look forward to receiving your emails.

Paul Hardley
