The Precision Raceworks X3/X3M (G01/F97) Stand Alone Auxiliary Fuel System is the highest performing and most stable low pressure fuel system on the market! Forget about how things have been done and embrace the benefits of dedicated fueling for your port injection!

Since direct injection came out on modern BMW's, enthusiasts have been adding port injection.  With this came the need to upgrade the low-pressure fuel system to keep up.  Historically this was done by increasing the output of the main fuel system.  Unfortunately, the main fuel pump is controlled using PWM by a factory programmed controller designed to reduce output when target fuel pressure (typically 5 bar) is exceeded, creating a constant battle when pumps are added or upgraded.  This limits upgraded fuel pumps from performing to their full potential. 

Additionally, the high pressure pump control system dumps fuel back into the low pressure system at high pressure low volume resulting in oscillations of the low pressure fuel system.  Because of this the DI system in the car is required to constantly make corrections to keep target AFR in check.

With this stand-alone low-pressure fuel system dedicated to your port fueling that is a thing of the past!  Get rock solid fuel pressures at any pressure, run fuel pressures which are 1:1 scalable to boost pressure, flow more fuel with dedicated lines, run smaller injectors and still get more fuel than you did with large injectors (allowing for higher resolution), put less demand on the car’s DI system to correct for fluctuations in pressure, even your tuner will be grateful as the system makes tuning of port fueling even easier and more accurate, the list of benefits goes on and on!

Essential!
Style: 19 Pack
After about 2 months of daily cleanings, the side brushes were looking a little ragged on my Eufy 12. The brushes included in this kit did come out a little bent, but as shown on the product page, when I dipped them in hot water they straightened right out. Intrigued, I decided to try that with the original brushes. They cam out looking like new! The only con is that the filters don't look like a perfect fit. The foam seems very minutely smaller than the original and the pleated filter seems slightly thicker.

All items fit the Eufy 30C perfectly.
Style: 19 Pack
We bought a Eufy 30C several months ago. After each time it is run, I clean the dust collection chamber, brush dust out of the filter and from the sponge-like pre-filter. After several uses, the filters simply were becoming clogged with tiny dust particles. This kit holds 10 filters and pre-filters, 8 brushes (or four sets) and one main roller brush. Every piece fits perfectly. They look and feel like original quality materials. This is a great set of replacement parts to keep your Eufy working like new.

My house has never been so clean!
Size: 05-11S
As a neat freak, this has been one of my favorite purchases recently. Hands down. No doubt. Our house has seriously never felt so clean. With four boys coming and going, plus a cat, plus my wife and I both working out of the same house, this place gets dir-r-r-r-ty! But now, I just set this little baby up and get it goes to town. Note: the first several times that we used it, the machine's debris holding chamber was LOADED. We ran it until the battery died (and it returned to it's charger automatically), emptied it, and then ran it again as soon as it was fully charged. But each time that it ran, it was completely full! Every single time. None of us can believe how dirty we were living. Note #2: We now take it upstairs to do a deep cleaning there. We had a little bit of a learning curve to make sure that all of the electric cords and such were off the floor. (They untangle easily, btw, if you forget). My son with the cat had a room that used to smell terrible... it smells almost normal after we ran this several times through there. And the volume of cat hair that this thing picked up is crazy amazing. Hair that we didn't even see. I didn't know cat hair smalled badly, but it must've. Room smells pretty decent now (not perfect - there still is a smally boy living in there)! Note #3: We keep a pretty clean house. That is what is amazing about this thing. It makes it really clean. Note #4: After the first several runs, make sure that you clean the roller brush. It will make a difference. The tool that comes with the unit that looks like a comb does a great job. If you get hair or thread or similar wrapped around it, use the handy dandy letter opener-style cutter to easily and safely clean it out. The blue parts on bottom around roller remove easily for deep cleaning. Do it! Easy and worth it for better future results. Note #5: Does all types of floors really well. We have ceramic, vinyl, short carpet, marble, deep carpet - all on the first floor of our house --- NO PROBLEM for Eufy! It moves with ease between them all. Note #6: Problem areas? We have a screened in porch that has a door that allows tiny little leaves in under the door. I'll just set the Eufy out there and forget about it. When I see it again, the machine has run out of juice and the floor is perfectly clean. Or my basement office. Set it in there at the end of the day, close the door and forget about it. In the morning, the floors are clean and the machine is sleeping where it ran out of power. I take it back upstairs, empty the cannister, and put it back on the charger. Last note: It gets in tight spaces. It cleans edges beautifully. It spends more time on a room than we ever would, so I guess that is why it cleans so well. It gets under most of our furniture. Around most of our chairs. And oh - I almost forgot - this vacuum is SO-o-o-o quiet. With our upright, you can't hear yourself think. With this thing, I can be do my work uninterrupted. Disclaimer - I have wasted a lot of time just watching machine in amazement and awe! Thankfully I can now walk away from it - although the 7 sessions with a therapist to get me to break the habit were a pain. ;) I highly recommend the machine - if you couldn't already tell! I came back on to Amazon to buy a unit for my in-laws and saw the opportunity to avoid my job for a little bit to write this review! Funny, but I am glad that I did. This little fella is totally worth it. If you are thinking about which brand to buy, you can't go wrong with Eufy. Kudos to the manufacturer and development team! Note to manufacturer: Can you please develop a machine to automatically climb and clean stairs (cook, do toilets, do laundry)... ? People, you are going to love this vacuum!
