Each to his own. Mods are generally done to improve certain aspects of a car's performance. Removing engine undercover or deciding not to replace one that has been damaged is a mod. Imo, this mod doesn't improve or benefit the car in any way that I can see. The engine undercover has been designed to protect the engine, hoses, belts, etc., and direct airflow. By removing it, you're just exposing the engine to any water/debris (salt, stones, pieces of metal, grit, grease, road kill, etc) that the front wheels kick up from the road. The last thing I want to happen in the backcountry is to find my S belt has been broken or knocked off the pulleys by some animal parts.

Good price for this one. Dealer's price is $225.00. They say it is a replacement so maybe not OEM, but if it fits, why not. Good return policy if it doesn't fit and they pay shipping back to them. I wouldn't drive without one. Why expose you engine to the hazzards and really, if you are driving a Lexus I feel you are driving the best. Lexus wouldn't of put it there without a reason.

I have mine intact on my LS but my Celica one flew off the freeway, I just haven't got around replacing it, I do however avoid puddles when it rains....most modern cars have them, domestic or import.

Okay, so how does one tell what generation Lexus one owns?

I know its been covered, but its buried in time.

Anybody have recommendations for an IN-DASH NAV UNIT for my 99 LS400?

i feel like i know the car would still run the same but i would feel better if i had it there so i am gonna check that website out to see how much it costs. I know it would be fine but what about if you go in water and it touches something electrical?? i mean it could cause a problem right??

.I 've seen some cars just plain stall due to owners like running over long stretch of deep puddle with speed...there's a wrecked/salvaged LS400 on ebay selling it for parts...check it out. It don't have to be new, just make sure all the holes are intact for mounting.

It's a splash guard, to protect any electrical components of your engine from splashing water, and other debris...it's a personal choice to replace it or not. IMHO, I would put one back just because I feel safer that there is something down there to protect the underbody.

Oh yes, I will get a list. Tom Williams wouldn't have a problem with that at all. They are above board. Probably one of the best Dealers in the country. Great list Lander. Thanks!

Does this deal apply to all Lexus dealer nationwide? I check mine in Jacksonville, FL and it's not in there.

Standard size is 7/8", 99% of oxygen sensors work with that size fine. Some sensors may feel loose but it's rarely an issue.

That's what I thought but not entirely sure, Thanks. ;)

Anyone know's the actual size of the socket to replace O2 sensor (bank 1-before the CAT) ?

Thanks for the input but I need to know the exact size, whether it's a 22mm or something else.I'm aware what kind of socket (wiring gap)you need to use but not the actual size. I read a post by one member that he bought a standard size sensor socket and it would not fit. Don't want to waste time getting the wrong one. Anyone here actually used one?
