From the drivers side you can reach blindly and pull out the grommet and screen, ( Use long woodscrew or dental pick.) Reverse to install.
Theres a vacum port under the upper intake. Follow the hose back too it, or reach up under the upper intake and feel for it.
You should be able to pull off the top plastic piece from the PCV valve. My hose pluggs straight down onto the valve. The plastic "two" port piece you don't need. You can cap it if you want. I take mine because the it works better witout it, hole bigger.

ITs not that bad of job just hard to see. Find some shade, get a ice cold pepsi and have at it.
