DIY: MPPK intake silencer mod

I had read that the MPPK intake was ever so slightly louder than the stock intake, but at over 300$, I thought it was ridiculous for a piece of plastic identical to the one already in my car, but with a hole cut into it.

So I took it upon myself to drill out a few holes into the stock OEM intake to recreate the perks of the MPPK intake.

Tools required:
- Flathead screw driver
- Step drill bit




Here's what the MPPK intake silencer looks like, with the parallelogram shaped red hole.


This is the part you want to get to and modify:




Step 1: Loosen the clamp, but do not take it off.
Step 2: Remove vacuum hose by squeezing the tabs and pulling it out, be careful it's fragile.
Step 3: Remove the sensor clip.
Step 4: Undo the 4 retaining clips.
Step 5: Pull up on the intake pipe to release it from the rubber attachment in the middle.
Step 6: Rotate the intake pipe up and out of the way, just to give you enough room to access the filter and intake silencer.
Step 7: Remove the OEM filter.
Step 8: Pull up gently on the intake silencer, it doesn't take much strength at all.
Step 9: Drill holes to your liking.


Step 10: Reverse steps to reinstall the now modified intake silencer.

I know some people might not be a big fan of this mod, but honestly, it costs nothing and provides you with pretty much the same benefits the MPPK intake does. Intake sound is increased by 5-10%, so it's very subtle. Pretty much exactly what I was hoping for. There is enough room to drill a third row of holes, but I decided to stick to this.

Comments and criticism welcome

When I remove my front bumper cover to remove the ACC sensor's visible stickers, I'm also removing part 15 from the intake. That mesh looks like it's only 50% open! Maybe I'll add one of those scoops behind the grill while I'm at it... :

Was thinking about adding one of those scoops as well ! Should help with airflow that's for sure. Not sure id remove part 15 it's meant to keep larger debris out, especially with the scoop I'd want to keep it in there ever more.

I am not too worried about debris finding its way in for two reasons.

1. There is still an air filter between the opening and the engine.

2. I had a much more direct opening in a past vehicle and it wasn't an issue.

Good points, I think I might get that scoop and remove the filter, should increase air flow.

Won't drilling those holes cause hot air to be sucked in?

Possibly, but I think it hardly makes a difference. Results in a sportier sound pretty much.

I like it. So does the afe intake or other brands will have a louder sound than this? Do you have a video for your car sound?

Put holes around the entire air box and it sounds pretty good. Just make sure you're doing it BELOW the filter. I'm probably gonna get a CTS Intake eventually but this was a cheap alternative if you just want a bit more sound, highly recommend

In case anyone reads this old post- the M Performance intake (in the bottom of the plastic airfilter box) has an extra hole trimmed in red plastic that is in the front of the box so it is actually pulling cooler air coming in from the front grills of the car. That's the exact same spot to drill or cut holes.
