Does anyone know if there is a OEM front underspoiler availalbe for a 99 V6 EX sedan? I've seen them for sale for a 2 door, will that fit my 4 door?

Honda did not make OEM lip kits for 6th gen sedans.

That's disappointing

If you want one bad enough, there are ways to do it. :)

...but it'll cost more than the lip...you'll also need the coupe front bumper. Then you'll end up with a slightly larger gap where the bumper meets the hood, and if that bothers you, you'll need the coupe hood as well. The gap isn't a big deal on a dark car, but on a white or silver it's a little noticable.
