: Thanks for the information on a high performance air filter replacement. I would like to know if there is a cone type high performance filter available for an 81 528i. I've seen ads for other years but nothing for an '81. Thanks for any help.
I copied and pasted a previous post from Tim Suddard. Here it is:

We just did the whole conversion in the May issue of Grassroots Motorsports using Kirban air intake stuff from an
E28. Big Horsepower gain!
Order it out on our website, see the results on our webboard, or look for it on specialty nesstands.
... I contacted Tim via email and asked for stands that will sell GRM in my surroundings, however none of the one
provided had it. So I missed the May article on GRM. He offered me a deal on a subscription, but I couln't
commit as I already have two subscriptions with other magazines. Not that his is not good, but is the wife who
doesn't want to see more car related "junk" in the house. (You may know or imagine how that goes...)
I was also wanting to know about this type of modifications to improve our already great machines. Eventhough, I
have posted mine For Sale, as many of us can make our minds up to keep it or to sell it. As I have had no responses
or offers, I still look forward to improve it, slowly but surely.
Perhaps one fellow E12'er read the article (Greg, Did you?) and can fill us in about this conversion. Maybe,
if Tim permits, it could be posted or put on the FAQ. (What do you guys say?)
