How do you replace a 2004 Honda CR-V air filter?

Answer 1

I just did this the other week. On the right side of the engine you'll see a box-shaped structure with a hose attached to the left side of the box. Here are the steps:
1. Take a phillipshead screwdriver and losen the clamp for the hose enough to carefully pull it off.
2. Use a socket wrench that fits the nuts on the box to loosen the bolts (I tried the phillipshead screwdriver and found it to be too slow and tedious).
3. The bolts are a 2 stage bolt, which means the threading has a smooth gap in the middle, you may think you loosend the bolt but there is one more stage of loosening left.
4. Carefully lift the air box up, note how the air filter is positioned and take it out. Replace it with the same size filter (get your filter BEFORE doing all of this of course).
5. Once it's in place, put box back down and go in reverse order (tighten screws and put hose back on and tighten that). That should do it. ONE SUGGESTION: I bought and installed a K&N Air Filter for my 2004 CR-V for $48.00 on autoanything.com. It's a LIFETIME air filter and you just have to clean it every year or so. I am NOW getting 29-31 mpg on the highway!!!! This was on a recent trip: mountainous and flat highway, 2 people, two 60 pound dogs in the back, suitcases in the rear seats- no roofrack on. Before I was getting only 26-28, mostly 27 on the highway. Well worth the money and suggest it to all owners.
