I know this sounds lame, but need to know how to replace....

[elm_tx]

I have a 2010 Nismo with Gen 3 Stillen cold air intakes with K&N air filters, dealer installed back in early 2011. Car has 42k miles on it. I'm thinking it's about time to pull the filters off and clean/replace them.

However, I don't see an easy way to get to them. The installation videos I have seen show pulling the entire bumper off to install the Intakes.

Is that what I need to do to clean/replace the filters?
Anyone have any youtube or other links that explain the process?
I can pay the dealership to do it, but would prefer to do IT myself.

Thanks in advance!!!

(gotta laugh every time a get a form letter from a dealership that NEEDS to buy my 2010 NISM0... No Chance In HE11)
