Any ideas how to retrofit a cabin air filter for 91 LS400
Just wondering if anyone had an idea how I could design a cabin-air-filter for a 91 LS400. I love my LS but I regret the absence of a cabin air filter (which wasn't available until the 93 model year). I'm not sure how different the duct work is between a 91 and a 93 and I'm not sure where I would put a filter. The 3 ideas I came up with are:
1) Swapping some duct parts from a 93 into my 91 to enable the use of the filter. This doesn't seem likely, but does someone out there have any knowledge of the differences?
2) Finding a suitable location in my 91's duct work to insert a homemade filter
or
3) Desiging a filter and placing it in the air intake beneath the cowl.
Appreciate anyone's ideas or experiences with this. Thank you.

Thanks trukn. I realize the idea of using an alternative filter has been discussed at length but was really interested to see if anyone (including newer members) has found a way to incorporate a filter in pre-93 models that do not support a filter. I checked my 91 LS beneath the glove box and it does not have a slot for the filter, so was considering my options for how to install one (e.g. beneath the windshield cowl like other cars).

Thanks for the reply. Yes, I too was hoping to find the slot in my 91 LS but it wasn't designed in yet apparently. I wish I had a parts layout to compare the 91 to the 93 to see if there is a way to do it by swapping in parts from a 93 or 94.
