M35 Aluminum Under Tray - Test Fitting

[DaSerb]

According to infinitipartsusa, splash shield part number is the same for all m models years 2006-2010. I am not sure if that means same fitment?!?!

if part number is the same - generally everything matches up. However, i know the AWD has different subframing because of different suspension, and different engines might need different location for oil access door.

[RM450GT]

any updates on this?

[tollboothwilley]

did our second fit - missed a few things but making adjustments. should be ready soon.

[Wangtang408]

Can we get an update on this? Thanks!

[Ilya]

Also interested in this. My stock one is getting torn up...only held on by a few of those bolts. What is the price on this? If it's reasonable, I will get a new lip (that plastic piece that comes off to get to the main shield), new bolts, and this thing. The best benefit is the oil door...I HATE taking off the cover just to change my oil...such a nuisance.

Please update us. Thanks!

[tollboothwilley]

Shop is cutting the latest version for me - Need to verify accuracy of fitment - but I believe this will be the final version for the RWD version at least. the X may have some differences - especially for oil filter location

[Wangtang408]

Hey Tollboothwilley,

Will the under tray be similar like the G35 that you have posted on your FB page.
Will it stick out from the font bumper kinda like a lip? If so Ilakol you wont need to replace the plastic lip.

[Ilya]

The lip I am talking about is the one you can see in this picture, it is most visible in the middle of the bumper at the bottom. It goes down a bit, but doesn't stick out from in front.

I know what you mean but IF the aluminum tray that Tollboothwilley is designing is similar to the pix on the G35 (above)t hen you wont need that plastic lip.

[Ilya]

I actually would rather the shield not stick out...but maybe it would grow on me.

I guess we'll see how it turns out for TollBooth.

The plate does not stick out like that, the one that that picture Wangtang posted is a different product. The product you see just above is called a splitter:

As the front of the car slows down the air without a diffuser, this is the ideal place for an inlet. A splitter is commonly used here, serving to increase the amount of downforce at the front of the car. The airstream is brought to stagnation above the splitter by an air dam, causing an area of high pressure. Below the splitter, the air is redirected away from the stagnation zone and is accelerated, causing the pressure to drop. This, combined with the high pressure over the splitter, creates downforce. The larger the area of the splitter, the more downforce is generated.

That's good news, than Enigma!

[Ilya]

That's what I figured (that it was a splitter). Thanks for confirming.

[vasekvi]

Looks great. Id like to see price info and fitment pictures, and confirmation on if it is compatible with the oil filter location on my 08 M45.

Considering skid protection vs the stock plastic, what if I scrape it and it bends? The stock plastic one bounces back (or breaks off right) but would this one bend in and then be in the way of anything and cause clearance issues with engine components?

[tollboothwilley]

Yes - as mentioned - that pic you pulled from the FB page is the aluminum splitter for the G35 which replaces the front piece of the under tray.

The aluminum under tray looks like this mounted:

[Ilya]

Hurry up and finish the product. Do want .

[vasekvi]

Drooling over here.

I think I can get my car to my friends shop to use his lift and take a picture of the underside of my M45

[tollboothwilley]

Do it. Can only help determine Fitment for you 45 guys

[tollboothwilley]

Here's how it looks - installed it on Mike's car today

[vasekvi]

So beautiful. I still haven't gotten on a lift to take pictures yet. I definitely want one.

Doesn't the original go across the entire bottom, why doesn't this? And why are there slots and holes in it; won't that build up grime on the inside?

[Larz]

I'm sure this piece would be much stronger than the plastic sheild we have now, and it has a door to make oil and filter changes much much easier. Having said that, I see two issues that prevent me from buying it.

1) There are slots in the sheild which will allow rain, dirt, and road debri into the engine compartment.
2) It isn't wide enough to reach from one side to the other which also leaves us with filthy engine compartments.

I'm hoping that picture shows the G-model sheild mounted on an M- model and the actual finished product will be the proper width and, hopefully, no slots or holes that allow dirt and grime to collect on our belts, hoses, and engines.

[EniGmA1987]

The slots up near the front are for some random pieces to fit through. Not sure what they are for as I have never seen them used, but on each side of the engine bay in that area two metal hook-like pieces jut down. They fit through those slots on each side. Even the stock plastic tray has this.

The slashes in the back are for design I think, and it looks good. Also maybe to help going through deep puddles. They are far enough back that things wont be getting near the belts if they somehow make it through these "holes".

The circle holes up front kinda have rubber pieces that fit down though them and block up the hole when the piece is mounted.



As for the width, it is the same size as the OEM plastic piece. Im sure it would look a bit more "complete coverage" if the plastic fender liner pieces were there. The plate covers the entire underside of the engine compartment and the area you see up into is over by the very far side of the car in the fender area.

Ok I got my car on my friends lift while I was consulting with him over exhaust options.

I don't see any door for the oil filter. I have yet to change my oil so I don't even know where the filter is yet.

This is the same width as the original - Mike just doesn't have his stock wheel well liners on. The slots are there for VENTING air - can easily be removed if thats what people prefer.

Some of the slots on the front section are, like Mike said, there because of the stock piece in the way. Some of the holes you see allow the lower radiator mounts to sit through like they should and wont affect debris. One of them is for the coolant drain which is in the stock piece.

I don't see any door for the oil filter. I have yet to change my oil so I don't even know where the filter is yet.

Stock tray doesn't have an oil door

The G-series shield doesn't mount to an M. As for the other things - see above comments.

[TDot]

Ok, I see. I'm considering this because I plan on dropping and see people talking about the stock version drooping. I would personally prefer no unnecessary vents/holes...looks underneath the car is meaningless to me. As far as venting air, if stock didn't see the need for it in a place like this then I don't see the need, just my opinion. Good work overall.

Agreed.

Do we have a price yet?

Holy Mary !
First, please accept my humbe apology for posting incorrecy information. I was not poo-ing on your work or expertise in any way - I was just simply dead wrong and I apologise sincerely.

That said,
I agee with the others in that I am not a fan of extra vents - just a copy of our current plastic part BUT with the addition of the oil door.

[tollboothwilley]

Has anybody compared part # for AWD guys? I have a feeling Infiniti made them a special version.

I need to double check pricing for final version but it seems like you guys prefer no vents. I will remove all unnecessary stuff including the Mt Fuji probably then.

Most people gonna want them in raw aluminum or will a lot of you guys want powder coated black to match stock?
