So I've browsed this thread and did some minor searching. But, my Tacoma is due for it's first smog check this year. I have a drop in K&N filter. Will this be a problem when getting it smogged? It's been a while since I've had a smog check done and I'm not sure, do they do a visual and inspect the filter? No stickers or anything else that would make it look aftermarket without actually looking at the filter. And I'd guess tail pipe emissions wouldn't be much more either, but wanted to verify from anyone who has smogged their V6's with the drop in K&N!
