A few days ago I was surfing the internet and found a picture of a 5.7 challenger intake manifold that was "shaved". It had all the molding ribs sanded off and painted Hemi Orange. Has anyone else on this forum done something similar to their 3.6 intake manifold?

Yeah i know you can shave the inside but I was wondering if anyone took the ridges and spines of the outside of the intake and made that part of it smooth

I'm headed to my garage to snap some pics of my other intake manifold. That's a lot to remove to get it to look smooth like the ones on the V8's

Hey bignibb I dont have enough posts yet to answer your PM but thanks for that idea but as of now I'm not really looking for performance mods yet. Maybe in the spring/summer time if it's still around we might be able to try that.

I don't really want to run an engine cover. Does the cover really have a useful purpose? Other than covering up the engine

Well it is time for this thread to officially get started.
My plan for my upcoming posts is to document and show how i go about "shaving" my intake manifold. I am looking to mimic what some MOPAR owners do to their 5.7 HEMIs, remove unnecessary plastic from the top of the manifold to make it smooth.

to this

And for me ill be starting with this

This may seem like a daunting task, but I'm going to take it slow and remove as little plastic as i need to.I purchased a used manifold off eBay so my car will have no down time. I did a test cut on one of the ribs two nights ago and a sanding drum on a Dremel tool eats the plastic like butter. SO speed on this project is not a priority.

So far i have about half of the top ribs cut down and first stages of sanding it smooth. I actually found that using the sanding drum is not ideal for removing the ribs. As you might be able to see the sanding drum remove alot of material leaving slight divots in the top of the manifold.

Using a fine tooth hobby saw i had from doing plastic model planes a few years ago removal of the plastic was a breeze. I worked in small sections cutting down the middle of a rib, then at an angle to remove a triangle shaped piece. It will take longer but as i said i have no downtime for my vehicle.
Initial cuts with fine saw
