CAI solutions - teg filter on Max, better filtration than K&N
What's up Max bros!
I just got a PRCAI and immediately had several concerns:
- fitment issues, cluncking noises, physical stress/strain on TB
- don't care for any filter I can see through, like the K&N
Here are some ideas I came up with to address these concerns - hopefully some of you will find these useful.
Here's a side by side comparison of the Purolator air filter for an Integra vs the K&N used in Place Racing's CAI. I've found this filter flows virtually as well as the K&N, but it will filter A LOT better. You can't see through this one!
I attached it to the upper CAI tubing using a 3" to 3" rubber coupler from Home depot.
Since it's a paper filter I didn't want to use it within the fenderwell where it could get wet so I decided to do a "hybrid" install. It fits perfectly. You can also see the piece of tin foil I attached to the stock scoop to better direct airflow to the filter.
I incorporated the accordion section from the stock intake to relieve any stress on the TB and allow for some give. This eliminated all the cluncking noises (used a dremel to cut the CAI tubing). You can also see the rubber elbow pieces I used to better attach the vacuum hoses.
In addition to leaving the stock intake scoop in place, I ran 2 1/2" shop vac hose from the fenderwell (through the hole I'd previously drilled for the lower piece of the CAI) to right under the filter. You can see the shop vac hose in the lower right, under the fuse box. This set-up gets plenty of cold air to the filter. After driving around for about 45 mins in 80 degree weather, the MAF and rest of the CAI piping actually felt cool to the touch!
Overall I'm extremely pleased with this set-up. I haven't noticed any trade-off in performance from the full CAI (upper and lower piece with K&N filter). Air filtration is way better, which was my main concern, and there no longer are any cluncking noises nor fitment issues!

Wow look at all that fancy vB code 
Looks good, I always thought the according section looked like it would case turbulance in the airflow but I guess it is better than clunking noises. In my fourth gen the according section has a slight bend in it (stock intake) which looks even more restrictive to me. Hopefully I will be getting a CAI or hybred intake soon.
