This kit is spot on for addressing many of the pesky issues with the MSM. It looks amazing, it sounds amazing and most importantly it performs amazing!
I sourced a 19mm (3/4 ID) 45 degree elbow ahead of time as recommended by the reviewer below. My stock one disintegrated upon removal. I also sourced replacement silicone hoses on the output to intercooler and routed my hose to the BOV a little differently. Some of my stock hoses were pretty marred up from removal (Mazda glues some of them on!) so I picked up some nice silicon replacements when I got the 45 I needed to replace.
I went a little wild with the metal couplers and got them powder coated to match my intake cover since I was doing that anyway as part of a timing belt replacement.
It’s totally a DIY job but you likely have to make a little adjustment here and there based on your car. Oh and FM’s instructions are spot on. Frankly the hardest (due to access) part is the O2 signal modifier - just not a lot of space to work. Having the car elevated helps, as does taking out the front seat. Note I did a wash water relocation too.
Great product from FM - couldn’t be happier!!!
This intake system is amazing, should have bought it years ago. Power delivery is much smoother, no more “light switch” on and off for power. Intake noise is louder (and better in my opinion), and listening to the recirc valve on shifts is fun. Because the power delivery smooths out so much you do lose some of the character but the noise replaces some of that, and I’m sure adding more boost more than makes up for the rest. One thing I would suggest sourcing ahead of time is a high temp 3/4” 90 degree hose to replace the stock unit off the factory bypass valve. Mine split on removal and there are plenty of affordable ones out there.
This completely transforms the car.
First off, you should buy a boost gauge with this kit, it will help a lot when messing with the boost controller.
Also, I will say that I did not notice any difference with the O2 signal modifier on or off. But your experience may vary.
You get more power sooner in the revs and more power overall.
Of course the best part is you get to hear all the beautiful turbo noises and the sound of the bov/recirculation valve.
WOW! Took about 4 hours to install because there were some questionable previous mods from the previous owner... but this kit transforms the MSM. If you're looking for more power and some awesome turbo sound - get this kit first.
I said in a previous review that it caused problems with the MAF. It doesn't. I was misreading an error code for the MAP sensor which was caused by my own error. I even reinstalled the oiled filter, no problem (probably should let it air out overnight after you remove the plastic, though, because I do think that initial sluggishness was the MAF sensor).
