Z1 Motorsports 350Z / G35 Aluminum Undershroud

starstarstarstarstar_half 4.9/5 - (68 Reviews)
Fits models: 350Z / G35

Product Description

The Z1 Motorsports Aluminum Undershroud for the 2003-2008 350Z and G35 was developed to replace your stock plastic or missing undershroud with a rigid aluminum panel, increasing front fascia rigidity, improving air flow, and making oil changes easier!

The stock undershroud on your Z / G was designed primarily to protect sensitive under body components from weather and small road media, unfortunately these plastic panels are not very strong and are susceptible to damage. The Z1 aluminum undershroud provides far more protection than stock by providing more rigidity and durability than soft plastic undershrouds. The boxed and skirted mid-panel further improves fascia rigidity.

Removable Service Panel

In order to service your car the undershroud must be removed. If you don't you'll likely find yourself reaching through a small rectangular hole hoping not to cover yourself and your undershroud in a thick film of oil after removing the oil filter and drain plug. This is no easy task. The Z1 Undershroud has a removable service panel, considerably larger than other similar undershrouds providing you with easy access and plenty of room to spare!

The removable service panel features large vented louvers, helping improve air flow on both sides of the panel and evacuating lousy heat.

Now available in two finishes!

  • Aluminum
  • Anodized Black

Features:

  • Large Removable Service Panel
  • No More Messy Oil Changes!
  • Louvered To Extract Heat
  • Includes Hardware
  • Improves Air Flow

Fits:

  • 2003-2008 Nissan 350Z
    Including NISMO and Roadster!
  • 2003-2007 Infiniti G35 Coupe
  • 2003-2006 Infiniti G35 Sedan
    • Does NOT fit AWD G35X models!

Installation Note: If you're installing this on a NISMO model or vehicle with NISMO fascia you will need a front extension panel not included with the undershroud, but available HERE.

Questions our customers have asked

can this be used with the kuruma z front bumper?
Absolutely will Victor, the Z1 Undershroud will fit any fascia that uses a factory-style undershroud, like the Kuruma Z.

Great product love the added stability shipping was fast unfortunately box came open some confusion as to whether all parts were there instructions were missing but is he one emailed them to me I love the part and it looks great although nobody can see it I know it's there very first upgrade to I'm sure will be many for my Nissan 350 Z hit a curb stop the first night I owned the car drove from Michigan to Las Vegas South was very tired when I stopped and just wasn't paying attention was going to do the upgrade very quickly anyway but had to do it before I could drive the car again thank you Z1

Pretty cool and solid. Definitely better than the stock oem version however, I feel as if it's missing some key coverage on the sides 🤷‍♂️? Another plus is that when you drop a nut or bolt or tool, it's much louder so you know if it went all the way or not.

Stock one takes forever to take out. This one makes oil changes a breeze. The panel under the oil pan can be removed super quick. A must-have for anyone who will be getting under their car.

Easy to install. Fits perfectly. Now I just have to remove 2 bolts to open the service panel for oil changes. The large removable service panel opens wide to give you open access to you oil filter. This is a good purchase for your 350Z!

You gotta have this for your G/Z! It's very well made, protects your engine and stiffens your front bumper a lot! Oil changes? It's literally just 2 bolts, then you have access to your oil filter, oil pan, etc. The only thing I didn't like about it is that it didn't come with instructions, so one can get confused with the bolts and washers. All hardware is there, the 2 long bolts go up front in the middle, just for folks who don't know. But other than that it's an very easy install, takes like 10-20 mins.

A very sturdy piece that protects the bottom of your car. Easy access to the oil filter and light weight. Z1 has done it again! Highly recommended over the OEM plastic piece of trash that will get caught between something on the road and thrown in the trash after being torn for the under belly of the your car.

Couldn’t have gotten a better mod done to my g, I lowered my car, surprisingly the same time my city decided to do road work everywhere and driving on these roads have been a pain, I’ve scraped at almost every location I go to and I’m only 3.5” off the ground. I will say this has saved me hundreds of dollars, if not thousands in repairs from debris I’ve ran over and the uneven lanes here. This isn’t a bot, this is a real dude telling y’all, get this whether you’re car is lowered or not and you’ll notice how much this has saved you.

I found this to be great installation. I'd recommend that anyone installing this product, make sure your inner fender wells are in good shape. I ordered new ones before I installed this Undershroud and it makes a huge difference because if your old ones are damaged, especially where your holes are to support this Shroud, you may regret spending the money on such a nice Shroud only to see it dangling because you did not verify the state of your old fender wells. Just a suggestion.

Great Product! I am new to the G35 and even with my bumper mounting points tore up I was able to install it with ease. Since Z1 is always looking to improve their product line I would just ask to change out the hex head bolts for button heads. This would be great since the cars are so low and the hex heads grab and bend easier. Maybe offer some type of washer/bolt kit for guys with tore up bumpers that aren't ready to upgrade the bumper they have. Keep up the great work!

Clean, simple, easy install, my stock plastic one on my 08 350z had gotten all beat up over time, this not only looks much better, provides greater protection, but also has a much better opening to do oil changes. And there were zero fitment issues with my z1 oil pan spacer!

An easy upgrade to do for the Z. Fairly straightforward to assemble only tricky part was the placement of the plastic spacers and different bolt length . Google / YouTube came in handy , wish it did come with some printed material.

Absolutely LOVE this thing. Perfect fit, and super easy to install. It's taken a few beatings so far and is still in great shape. Oil changing is a breeze and it makes it easy to work on a lot of other stuff in the same area. Includes all hardware and the nylon spacers are a great addition to keep things flush. 10/10 would recommend.

ABSOLUTELY LOVE THIS UNDERSHROUD THE FINISH IS AMAZING AND I LOVE THE FACT THAT ITS ALUMINUM. I PUT ON A FRONT SOUL FUNCTION BRACE AND THEN THE SERVICE PANEL SHROUD ON!! OF COURSE IT NEEDED SOME FORCE TO HAVE THE LONG EXTENDED BOLT INCLUDED TO BOLT ALL THE WA IN BUT IT DID WITH NO MODIFACTIONS. ALSO IT DOES FIT THE AUTHENTIC NISMO V2 FRONT BUMPER

Love the fit and function of this piece. Leaps and bounds better than the plastic OEM splash shield. Only negative thing I have to say is that the hardware kit is kind of random with no specifications as to what is recommended to go where. It's a little overkill for something that screws into plastic fender liners really. I'm pumped to change my oil the next time!

Nice upgrade from the OEM plastic! Solid, great fit and finish. Only one recommendation - might want to supply two longer screws (+ 1/4"?) with hardware kit for two center holes where front pieces fit together. Easy fix, but couldn't get supplied tapered screws to start. Had to use a couple old, longer OEMs.
