Most K&N filters are just the air filter itself. While they do make units to replace airboxes, that isn't something you will find for a D. As to the air filter itself, there isn't an EXACT replacement K&N unit. There is one that is VERY close, but would require some modification to make it work. Basically it's just a little too small and would allow air to leak around it which totally detroys the whole concept of an air filter. More info is in archives including the part number. I happen to know that a fellow list member will be offering a kit in the near future that will include this K&N filter along with all necessary parts to use it in a DeLorean and have it work properly. Bob Brandys sort of mentions it in his Dyno Day post. The kit was tested there to find out what sort of HP gains it offers. I don't have any more information on it right now, and no pricing info yet. There will be a post to the list sometime in the near future.
