Yesterday I completed installation of the Mina intake tube to my XJ 3.0 AWD at 136k miles. My stock intake was partially melted during a cooling vent hose leak at the beginning of the year, so I figured an upgrade was in order.
My feedback is mainly around providing a step by step install recommendation. It took me nearly 3 hours of trial and error instead of 30 minutes I had hoped! I also chose to install titanium fiberglass header wrap to keep the intake temperature down. I learned from others on here that the intake temperature rises with the aluminum pipe. Mina recommended keeping the wrap off for aesthetic value and that header wrap was only needed if the pulley upgrade and tune was ordered with the intake. My key installation learnings were:
1) The center rubber hose connection needed to be installed first since it fit very snugly compared to the stock intake.
2) Then getting the center tube inserted was next most important, although I was unable to insert to full depth due to the driver’s side air box connection.
3) The back of the intake tube rubs on the drivers side intake funnel pretty well during install.
4) The clearance of the passenger side tube is close to the supercharger pulley but no contact so all good.
5) I cut the drivers side vent hose connector to length and secured with a plastic zip tie around the connector.
6) I left the passenger side rubber cap on the small vent tube. My stock intake was plugged here.
So far it sounds a bit different, and my butt dyno feels like the car has a bit more pep early in the rpm range. My intake temperatures are in line with my previous stock ranges after a couple highway trips, but I need to test it around town as well. Now I’m hoping to install some K&N high flow filters to the air boxes to help a bit more with intake temps.
**Below is the installation order from Mina’s experts after I asked:
We make a lot of intake kits for the Jaguar model range and the V6 models have the tightest and most tricky setup. The placement between the throttle body and air filter boxes is pretty unforgiving. 1. Take off the factory parts. 2. Place the throttle body coupler and clamp down to the throttle body. 2. apply some lubricating spray on the very edges of the right and left tube and slide the 2.75" straight covers over the tube. 3. push in the tube's center pipe into the center coupler, but do not tight down. 3. position the tube so it gets are close to the maf sensors as possible (it will likely will not line up exactly, but as long as its close). 4. slide out the couplers and connect to the right and left maf sensors. The air filter boxes have a bit of give and can move slightly to allow for a connection. 5. clamp down the right and left couplers. 6. clamp down the second throttle body clamp. 7. lastly use the provided black hose as a union between the factory breather hose and the new tube's breather connection. It will likely be longer than needed to mark and cut. I know this is a lot of information so if you have questions please don't hesitate to contact us.
Really unsure about the M/ gallery intake, it was the first mod I added to my X351.
A few years later saw a YT vid on a tuned XJ showing Dyno pulls with the MG versus stock intake on tuned super v8 in Britland, was surprised when the Dyno pulls showed a drop in HP, the hypothesis was the duct tubing on the MG intake although shiny and pretty, did nothing for performance due to the drop in airspeed velocity and the round cross section.
The advice was to do not ditch your original intake assembly. I guess we can look to blame heat soak etc, but at the end of the day its up to us as owners.
Never really noticed mine as being noisy from SC whine, people make it sound like its so noisy, like driving a top fueller around or nitro funny, Nothing is further than the truth even with a VAP stage 2 crank pulley, and ecu tune with a few 200 cell racing cats, its virtually undetectable unless you are pulling 2nd and 3rd into 4th at hard acceleration from around 3000rpm up, and if you are driving like that with passengers on board, well I will say no more.

Looks pretty though, mine is still installed.
To get mucho more SC whine you need to replace the stock filter boxes and filters with cone filters.
This works a treat on the F-Type where the filters sit below the engine bay in front of the front wheels (I can attest to this!) and there is no "hot air intake" effect from sucking up air from the hot engine bay, but unfortunately not so on the XJ (and XF). Plenty of XFR and XJR owners have tried replacing the stock filters/boxes with cone filters and I can't recall a single one of them that reported no loss of power.

Thanks for your reply Lightspeed. I know there’s some discussion about this comparison being set up unequally in the XF forum (see reply #10) https://www.jaguarforums.com/forum/x...-users-245055/. Ultimately I ordered the Mina after reading the dialogue and deciding that it looked better, I could avoid heat soak somewhat through wrapping with header wrap, and my existing OEM tube was melted at the throttle body connection.
As I described, it’s not a perfect fit and required some finesse (took me longer than the advertised 30 min!), but it has been solid for the past couple months since install. The whine was noticeably louder after I started running with my engine cover off to minimize air intake temp, with it on there was not a huge difference unless you described >3000 rpm.

@griff831 , don't sweat it mate, I have kept mine on despite also still having the original too, it is a nice difference in looks breaking away from all that black plastic under the hood, having 560+ bhp in mine its no big issue as I rarely drive mine anyway.
Sad to hear your original succumbed to heat damage, but for a looks change versus a small hp output drop its a fair call to go with the Mina, the polished alloy does look pretty flash.
Mina. As stated they are not as simple for fitments, fortunately the are enough joints in the ducting to make it happen with a little patience.
Enjoy the car mate, they are a beautifully balanced tourer, especially regarding the wheelbase, mine still steers on cornering extremely well despite the size and weight class.
And if you ever really want to hammer the sports thrill, just drive on 1/4 tank, its amazing the extra performance gain just by dropping the fuel load.
The original air intage setup are good at least 575HP (max tune JLR made themself)
As everybody know who are tuning engines (and maybe racing) that engine ai rintake its just not so simple that make smooth bore. Depends what you are looking from engine, you might want to have whrils on airflow. Also backlash shockwaves can make direct piping difficult to work in optimum.
On this power level on the street car, the gain or lose 20HP is not a big deal anyway, you see it only in dyno. Better sound by tune intake is a gain as well and this can increase "assdyno" value much more HP than actually losed. So just enjoy.
