Aftermarket glass is usually cheaper & thicker than OEM glass.

I went with aftermarket glass when I had to get my windshield replaced.

make sure meets or exceeds manufacturers specs.....If your window motor or anything associated with that goes out and your try to get it replaced under the warranty, mitsu will point to the non-oem glass as the reason unless it meets or exceeds oem specs

Look for PPG or LOF on the glass.These are two of the biggest producers of automotive glass products.They meet or exceed OEM.

aftermarket glass is not necessarily thicker, thinner, weaker, etc. In general it IS lower cosmetic quality in that it will have more scratches, chips, etc. All glass sold in the US has to meet the US safety standards- and that's it. The purchaser (Nissan, Mitsu, etc) says what cosmetic defects are allowed- no more than three scratches 2mm long, etc. The aftermarket does not have these tight cosmetic standards to meet so they scrap less glass and therefore it is cheaper. Sometimes thicker glass is lower price not more expensive (it is for windshield glass) because thicker means they break less and have a higher yield so cost is lower. I worked in an auto glass mfg plant and stuff that would not meet the OE cosmetic requirement we would often use for aftermarket if the OE allowed.

For door glass I would buy aftermarket with no hesitation at all. Just look at it first before it is installed and check for visible chips or scratches.

edit: there is a HUGE markup in glass, esp at the OE level. We would sell the OE mfg a windshield for $60 and it would list for $500+ at the dealer (this was 10 yrs ago).

Also note the "OE spec" angle is BS. The OE has a cosmetic spec and also a spec for the "form" (shape) and size of the glass. The aftermarket does not necessarily meet this spec because it is not given out to the aftermarket. The aftermarket makes glass by buying an OE piece and measuring it and reverse engineering- they don't have the factory drawings to meet their specs unless they stole them. The only specs aftermarket glass will meet (in general unless they luck out) is thickness (matches the original) and meets the federal safety spec (which they have to)- and that's all you need to worry about.

Hmm, when did you get your windshield replaced? I had mine done in December and at the time the only place to get an Evo windshield was direct from Mitsubishi in Japan.

My windshield is starting to get those perma-specks and I was thinking about calling my dealer to get a replacement. Thanks for the info Steve. You probably just saved me a couple hundred dollars.
