Default how to open the intake system? (black thing below the engine cover)
Does anyone know how to open the whole black thing below the engine cover?
I unscrewed 2 nuts, 5 hex screws, and 1 bolt behind throtle but I was not able to take it out. Any help/ instructions would be appreciated.

Thanks for posting.

You're missing a couple 12mm bolts.. one on the driver side i beleive, and the other towards the firewall. There is also a clip that holds the wiring harness to the back of the intake.

Thanks for posting.
Here is a link to some instructions for installing the F-Sport Performance Air Intake. Maybe this will help you?

I updated the link to this document

Nice, Time for a port and polish

I wonder how much HP could be gained by removing the VR-butterflies? Hondas had some gains by removing them in the past.

I am hitting the mark to change new spark plugs. The last two spark plugs from the driver side are under neat the intake. Wonder why they are hiding the 12mm bolt behind the intake?
If anyone wanna to DIY, I can provide some help with the pixes...

How many miles are on your car that you are swapping out your plugs already? What are you going with??
