thanks

Oh yeah, as for check engine lights, i dont know cause i already have one due to a secondary air injection gremlin that i have yet to fix but ill recheck the computer for any new codes later today.

I have the True Flow intake which also deletes this small muffler as you call it. No cell lights will come on. Its really nothing more than a silencer along the intake tube. I think if you look at Home Depot you should be able to find a circular cap/plug for that size hole. It will make your car growl more. Here is the area he is talking about. It looks like a small box that is connected to the intake tube. Inside of it you will find a white foam silencer. There really is no need for this part other than to quite down the noise level. In fact, this area being removed should provide better air flow. I would suggest buying a 90 degree elbow bend plastic tube from Pepboys and making your own intake tube. It's pretty easy. This will delete number 6, 7 & 8.

thank you for the picture. can't i leave it open, why even glue a cup to the end, if it's open anyways. does this make sense. if i get an elblow put on, i am still leaving it open. or am i missing a step. i am pulling the silencer out of the box, so the box is now empty. will i be putting the box back also. dumb questions...i guess when i open, i should be able to figure it out better.

No. You are right. If you buy an elbow silicone cupler and also buy an extra clamp, there is no hole left and no need for messing with epoxy or anything like that. Look at this picture. Simply cut the tube at the ribbed part at the end going towards the throtle body and add the new elbow at that end with the new clamp.

If you buy a silicone elbow and an extra metal clamp, after your install it should look like this.


Most aftermarket cold air intakes kit like the Evo and Trueflow come with these parts deleting the same box alone the intake tube. This is a very simple and inexpensive way to ad a more true air flow pathway to the T.B.

None that I know of. I've been making these in Photoshop from the PDF manual that I have on my computer.

Technically, it's called a resonator. The resonator IS the box, the foam inside is a secondary noise canceling measure. It's typical on most intake tracts. It's function is to capture pressure (sound) waves, bounce them around, and send them back up into the intake plenum 180 degrees out of phase, thus canceling some of the noises coming through the throttle body. It's like a passive version of those Bose noise canceling headphones.

It doesn't effect flow, so removing it will not change the performance of the engine. Removing it can't throw the check engine light.

What my directions say todo is to remove and discard part number 6, 7 & 8 completely...
The Epoxy in the cup will be jammed onto the opening circled in the picture... However once the epoxy is cured abit and almost solid, you peal the 2/3rd size cup off and the epoxy should stay behind stuck onto the opening circled in red.

Is this before or after the air filter? If after than I would be wary of your epoxy plug. If, over time it hardens and cracks, little chunks of epoxy could start heading towards the intake valves. Ugliness and tears would ensue. I think using the elbow makes a lot more sense.

Hmmm, i dont know... i dont see that epoxy cracking, i mean nothing touches it, no moving parts either and rated up 2500 psi before point of failure. I can see an airfilter deteriating sooner than the chunk of epoxy but your right about the elbow... does seem safer, But imma stick with the stock elbow its hard inner surface will probably help echo the intake noise alittle better than a softer sylicone elbow.

Heat + vibration + pressure from a hose clamp (if you're using one). I'd be looking for a molded plug.

interesting! now the part that i don't understand. the plastic cup and epoxy....am i glueing the cup somewhere...kind of confused. circular cap/plug doesn't help. if you could please explain this further. or pics would be amazing!!

i'm jealous i want to try tooo!!

i'm fairly good with my hands, so if you could make me understand in a better way.
