Here's an email I got today from Airaid...
You are correct the WK were 2005-2010, but they did make sheet metal changes through out the years. If they changed the hood area at all our system would not seal anymore. Also I noticed looking online that in 2009 they did make some design changes in the engine compartment area as well.
To me it seems like he's saying the issue is simply w/ the heat shield forming a seal against the hood, rather than any other fitment issues from the throttle body down. I sent him another reply to see if he can confirm.
GR33N D3MON, if you happen to snap a couple more pics, think you could also get a close-up of the area over where the filter/heat-shield would go?
I figure if there are any changes, I could always add some weather striping or foam to help seal... and even if worst come to worst and it doesn't seal perfectly, it shouldn't be that big of a deal.
I'll keep everyone updated
