Battery box works as it should.
Maybe the thumb screw rods that supply downward pressure on the plate could have a reinforced section of the box to hold on to as they pull up on the thin plastic from below. I found the battery could still move around and was scared of damaging the bottom of the box if I screwed the thumb screws too much. I might add my own reinforcement later on the bottom so I can really tighten the thumb screws.

To get my battery to fit, 2nd one from Mazda (a little bigger), I had to cut a section from the bottom of the battery, which was wider than the overall width of the battery to clear the thumb screw rod. The battery also had a plastic handle, so I had to trim the plastic ribbing off each end of the battery to get it to sit back further in hopes to give more clearance for the ECU.

Lastly, the power wire on the right, I moved 90 degrees so it sticks out to the right. The power wire with the main fuse I moved 90 degree so it sticks out to the left, however I straightened the metal tab as where the OEM bend was wouldn't allow me to fasten it back on. I added a new bend just before the fuse as it had to wrap over the edge of the battery. The metal didn't look like it was going to snap which was a concern.

After this I was able to close up the box. I did quite a few things to my car this past long weekend and that was actually the most difficult, weird right.

Corksport, I like the look of the box, I think it just needs a little more refinement. Maybe adding some additional instructions about the connections to the positive clamp of the battery to give more room like I did may help a few more people.
Looks nice, install was easy. however, it could be MUCH thicker, especially because of how much it costs.



impressed with looks, discouraged at how flimsy how unit is. namely the battery tie down post holes.
I love just about every Corksport item. While it does it's job well, I personally am less impressed by this one.



I would improve it by thickening up the bottom (possibly an aluminum base insert in the bottom?), so that box doesn't bow, when the tie-down bar is tightened and help it to support the ECU better. The inner side tie-down post is a very tight squeeze between the battery and the box wall.



Lastly, the description says it will accommodate a CS 3.5" intake. However, I have the 3" and it hit the ECU cover and cracked a portion off it. Overall, it could be a bit sturdier.



I am a Corksport fanboy. you know that. But I don't sugarcoat and I will always be honest. You don't have to post this review; just thought you'd like to see my personal review.
The box looks great. The install was kind of a pain but after I got the wires routed to was pretty easy.The box is flimsy and feels like its very fragile, the OEM battery box is thicker. Also if you don't have the battery that is in the instructions it won't fit. The Box could be made a little thicker especially considering the cost.
I had lost the cover to the oem battery box along with having a rats nest of wires from the ecu

this turned my engine bay from zero to hero in less than 30 minutes

very happy with my purchase and glad they did the development for it
box looks nice in car, easy install. The one thing the don't tell you is you need to have the oem battery size no aftermarket that are larger the box top will not fit if your battery isn't small enough. Another great product from corksport thanks again.
This thing...looks nice in the picture, and when it's finally installed...so to install it...wellllllll...



It took me all of an hour plus a little bit longer to get this into my engine bay. The ECU location looks so easy to deal with in the video, but my experience didn't match up in the same way(I wondered if this was a piece worth installing).



In the end I concluded that the battery in my car - a Mazda-branded cell - is slightly longer than the one in the posted video.



This has reduced the tolerances inside the battery box and therefore made it very challenging to cram everything together to bolt on the top.



Also in conclusion, I like the space now available between the battery box and the TIP, so I still think this is a part worth having.



That space can now be filled with a bigger TIP/SRI when the time comes.

The box looks great. The install was kind of a pain but after I got the wires routed to was pretty easy. The only thing I don't like about the box is that it's flimsy and feels like its very fragile, the OEM battery box is thicker.

2008.5 Speed 3, factory hood TMIC/Batt box ducting; I noticed the batt box port is lacking on the CS box, I can only assume this isn't a concern because you haven't included it in your design. At what point should I or might I be concerned about the ventilation of the batt box? Also, looking at my engine bay with the stock(!ugh!) intake box, it looks to me like the CS batt box might be a squeeze on its own (I know, CS SRI would solve that, it's on my 2do list hehehe, 1st things 1st).
