Kojem Engine Splash Shield Guard Compatible with 2007-2019 Infiniti G35 G37 Q40 Q60 (RWD only) & Nissan 370Z Silvery Aluminum Under Tray Cover Skid Plate

My OEM splash shield was cracked and rattled when I purchased my 370 Z with 34K miles. This aluminum splash shield is heavy duty and I love the oil filter & drain plug easy access panel. The washers are a little small for the mounting holes so pick up some fender washers with 1/4” holes at the hardware store. No instructions but I found it easier to mount the back piece first (all holes lined up well), then the front. On the front, 4 of the 6 holes lined up which should be fine because it’s way more solid than the OEM was. I drilled holes for the other 2 bolts which only took an extra 15 minutes. It’s now more solid than factory and looks great if you happen to be the Geico lizard to be able to see under there.

For only $100, this undertray is a steal. From what I can tell, this is an identical unbranded version of the $200 TBW Undertray. The unit I received had a small bend in one corner but that was easily straightened out with some vice grips and cloth. Considering that an undertray is just a flat piece of metal that protects other components from rocks and water, this product has met all expectations. I've had it installed for 5 months and I've had no issues thus far and don't expect to anytime soon due to the corrosion resistant aluminum. The hardware provided is the weakest link. It is coated but may begin to rust. Installation was a little finnicky but not difficult to do alone. I have not yet completed an oil change with the undertray on, but I expect that the oil door will make that a simple process.

Solid, and for half the price of bigger name websites...

Funny "Name Brand", why not Kojak? ;-) This one appears to be the same under several names on Amazon. It's Chinese (what isn't?!) and be careful for some sharp and jagged edges not quite grinded off. Bottom line, it fits although don't tighten bolts until all are started. Hardware is supplied, but it's not 10mm nor 11mm, it's somewhere inbetween and standard sockets didn't fit. There's a convenient panel for draining oil. Durability has to be at least on par with the crappy plastic shield it replaced and in my estimation, much better. I'd have to see the much more expensive options from the Z shops that do the same thing to honestly judge this one and its clones against them. It looks much nicer than before, but who crawls up under cars to ogle at the splash shield... For the price, you can't go wrong. 5 months later, (August 2024) I just did an oil change. Two 10mm bolts loosened and I was in business. Before, it required the entire plastic splash shield to be removed (PITA). If you're on the fence between this and the more expensive versions, save yourself the money and buy this one.

Purchased after finding out the previous owner did not have the tray. After 4 months of continued used the front section of the tray came off on the interstate and damaged the second section. If your going to get a tray I heavily insist that you go for either the Z1 or the ZSpeed under shrouds. Price is higher, but the added security by being bolted to the frame is a must, as well as the included hardware being rigid and having quality instructions.

For 100 bucks honestly this is a better deal than paying for the z1 undershroud. Fitment wise is however questionable. Yes some of the bolts line up perfectly and have no problems but most cases you either have to drill new holes or just zip tie it. Over all it took me about an hour to install. It doesn’t come with instructions but pretty much everything is self explanatory to you. Does come with extra 10mm bolts and clips if you needed which is handy.

Doesn’t fit properly and recently backside just popped off, horrible product doesn’t fit properly

Installed on a G37 sedan, fit perfectly with no trimming or drilling. It aligned with the factory subframe bolt holes and once torqued down the aluminum plate is rigid with no flex or vibration. Drain slots and service access points are correctly positioned. It’s a major upgrade over the stock plastic shield, which didn’t even have an oil access door. Ground clearance stays nearly factory and the coverage extends past the oil pan and steering rack. I swapped the included hardware for stainless flanged bolts and larger washers with anti-seize to avoid corrosion long term. The supplied hardware works, but doesn’t fully cover some mounting holes. Tip: you can line the top of the plate with sound deadening mat or underbody coating. This protects against corrosion and slightly reduces road noise.

When it's on at a good price it might not be too bad. Installed it on my 370Z Unit came with a bent corner but being thin aluminum it bent back by hand. The paint chips off really easy but it's aluminum so it won't rust and it's under the car so nobody sees it anyways. It fits decent but the included washers are too small so slip through the holes drilled on the plate. You'll need larger washers. No instructions but you really don't need them it's pretty self explanatory.
