DIY Air Box mods

[JoeHundredAire]

Anyone got any pics of DIY mods to the airbox & intake. I would like to smooth out the air flow & get a little better performance out of my PT.

There USED to be a set of pictures for the air box mod but it was posted on PT Cruiser World which is down right now and doesn't look good for coming back. That's the ONLY place i've seen pictures. Maybe someone here with the mod could take the box apart and take pictures of each stage of the set-up.

I found this one of mine. Chrome top piece is a basket used for grilling. Bought it at Lowes.

Has anyone had a noticable improvement in mileage or power a K&N filter? I'm just trying to make my little PT run more efficent. I kind of a DIY nut & just the kind of person that can't leave well enough alone I do the same thing with my aquarium hobby too

I went with Mobil One and a K&N at the same time, did see a increase in mpg, anywhere from 1-3mpg depending on usage. Even without a increase, saving $12 per filter change covers the cost of it.

I don't have pix, but what I did was pretty simple. Take out the white plastic piece that looks like a spool and take the fenderwell-to-airbox elbow off. Lastly, I blocked the resonator section with 20 ga. steel, and filled the resonator chamber with household type expanding foam in a can. Fond a slightly different sound, and some performance increase in the mid to upper range. My dyno is a particular hill on I-84 that I hit on my way to work.
Also found two kinds of air filters in my shop. One has a mesh grille on the top side and one doesn't. The one without the mesh tended to squeeze off the gasket rim of the bottom box, and open up a non filtered path. The meshed one didn't distort at all.

Maybe you would be willing to take some pics?? Post them here or a link to where you can put them at

Instructables - The World's Biggest DIY & How To Show & Tell

It would be a great service to us here in the PT community!

I put some pix and descriptions in an album on here. It's under nexium, and air box mod. I hope you can find them. I almost couldn't!!
Hey, it took me 3 hours to figure out how to stick that little picture next to my postings.

[JoeHundredAire]

I saw the pics that you had linked through your profile. I'll have to pop the hood & rumage around to see what my options are.
I have wed & thursdays off, so I may pull it all aprat then. "Scoot" got a good sponge bath yesterday so I can see where I need to apply some polishing compound & elbow grease toget some scuffs & scratches out. So it will be a good time to do all of it at once.

Thanks for posting the pics!
