The Precision Raceworks S58 Port Injection kit with stock manifold compatibility is Exactly what the new G80 M3, and G82 M4 guys have been waiting for! Safely add fuel to your S58 engine and get ready to hold on! This kit is capable of providing supplemental fueling to all BMW's equipped with the S58 engine so that you can push the limits without the need for purchasing an expensive custom manifold.

This kit integrates seamlessly into your car like it left from the factory with it installed. Our kit includes everything needed to add multi-port injection and is 100% e85 compatable. Purchase the kit with out injectors or with new genuine Bosch Motorsport injectors that have been modified & flow matched (both static and dynamic) rivaling the quality and consistency of even the best injectors on the market. A Detailed certificate of conformance is included with each set our injectors giving you all flow data needed for optimal tuning.

What makes the Precision Raceworks port injection different from others on the market?  Our fuel rail is AN6 all the way through unlike some other kits that have AN6 connection but have a much smaller bore reducing flow which can result in pressure drop at the injector.  The Precision Raceworks fuel rail is the only rail currently on the market that features locks which secure each injector to the fuel rail.  This removes 72+ PSI of force pushing up on the fuel rail preventing potential failure where the screws attach to the plastic intake manifold. Additionally the locks allow the rail to be removed without fuel going everywhere.

Precision Raceworks has been the market leader for port injection for late model BMW's for years and this kit will continue the trend. Featuring your choice of the same 750cc* & 950cc* injectors used in our other BMW port injection kits.  Our injectors have been used for nearly a decade by thousands of customers around the globe so you can be confident you will be happy for many years to come.

Best of all our kit comes complete, no need to source or make custom fuel lines.  No cheap rubber lines or plastic fittings.  Our lines are smooth bore PTFE for years of service life in the most extreme conditions and compatible with all fuels.  The same goes for our all billet fittings that not only look great but work great too!

Simply pick up this kit and pair it with your favorite injector controller!  We have several to choose from:

AIC-1 - The basic injector controller used for years.  This controller is easy to tune, and utilizes batch firing (all injectors fire at the same time)

ReFlex Lite - Simple controller that is similar to the AIC in price, but gives you Seqential fire of your injectors.  This improves fuel trims, fuel pressures are more stable, and each injector will output more fuel each time it fires.

ReFlex Plus - Advanced controller featuring CanBus integration, ability to add an ethanol sensor and integrate a true flex fuel tune, ability to add a fuel pressure sensor, and additional capabilites.

My Dogs Love This!
As a dog mom to two pups, I’m always looking for toys that encourage interactive play, and this one has been a hit. ✨ What stood out: ✔ Easy-to-grab handles ✔ Great for tug-of-war ✔ Flexible but sturdy design ✔ Floats in water ✔ Fun sensory scent ✔ Perfect size for medium dogs The dual-handle design makes it comfortable for both me and my dogs during tug games, and it feels much safer than trying to grab random rope toys. The material has enough flexibility to be comfortable while still feeling durable enough for active play. My dogs immediately took interest in it, and we’ve used it both indoors and outdoors. It’s made from a thick material that is extremely durable as well as chew resistant. My dogs go crazy over it! If your dog enjoys tug-of-war, fetch, or interactive play with their humans, this is a really fun option!

Quality materials, durable, and fun to play with.
This Pupstages Flex-Force tug toy is perfect for people who have two large dogs, like I do. The two-handle design is a great feature. It gives you a comfortable, secure grip during tug-of-war, which makes playtime feel more controlled. It’s also helpful if you have two dogs who want to play at the same time, because each can grab a side and get into the game. Another fun thing about the design is that the irregular shape gives it an unpredictable bounce that’s exciting for my dog who loves to fetch. The material is rubbery enough that it bounces well too. The material has a bit of flex to it, which helps absorb some of the pulling force instead of feeling rigid. That slight give makes tugging feel smoother and a little easier on both your hands and your dog’s mouth. It’s also more fun for my dogs. It’s sturdy enough for regular play, though as with most toys, extremely aggressive chewers may still wear it down over time. So far, I’ve been impressed by how sturdy it is. The material feels high-quality to me, like it’s made from very good materials. I’ve owned probably a hundred different dog toys, and this feels like one of the better made ones. One fun detail is the blueberry-apple scent. It’s not overpowering, but it’s noticeable enough to make the toy more interesting to dogs. I can smell it if I hold it up to my nose. Whether they think it smells like a gourmet treat or just “intriguing mystery object” is up to them, but it definitely adds to the appeal. The fact that it floats is a nice bonus. It opens up the option for water play, like tugging at the edge of a pool, lake, or even just retrieving it from shallow water. I have a tiny pond in my backyard, so most dog toys end up wet at some point. Size-wise, it works well for a range of breeds. It’s big enough to feel substantial but not so large that it becomes awkward to handle. It has some nice weight to it, while still being manageable for smaller dogs to carry. This is a fun, well-designed tug toy that encourages interactive play. It’s comfortable to hold, engaging for my dogs, and versatile enough for both land and water adventures. I think it’s a very good value at the current price.

Not for aggressive chewers but fun otherwise!
This flex tug toy is great for pups who loves tug of war! It is a softer material than I thought it would be, which does make it more likely to be ripped by aggressive chewers. I have a pitbull who would easily destroy this toy. Luckily, I have a smaller puppy as well, and he loves playing tug of war with it. The soft material makes it more comfortable to be held when playing. It also smells much better than most dog toys lol! The blueberry scent is great and definitely makes it more enjoyable for me to play with my dog, and he loves it too!

Durable + Fun Design + Smells Good Too
I chose this flex-force dog tug toy from Pupstages for my two Pitbulls. They like to wrestle and this seemed like a good option that would keep them from wrestling throat to throat. This sounds scary, but they never bring blood or even have slobber on their neck when they’re playing. I was extremely pleased with the quality of this dog boy and also the scent was bright and fun. I asked my husband to smell it before I told him what it was, he said it smelled fruity. The blueberry apple scent is pleasant and might keep it long-term from smelling like dog slobber. The materials used to make this feels very durable and it stretches easily. It’s also a fun way to play with each dog one on one or sometimes play with both of them while I pull on the other end. Even though my dogs are aggressive chewers, I don’t have any concerns about the durability of this toy. It will not be something that I leave for them to chew on when we are not playing since it was not designed for that purpose. If they accidentally get a hold of it, I don’t think it will be an issue short term if they chew on it. For the sake of comparison, I had a dog pull toy that I would have said was similar to this one. When this pull toy from Pupstages arrived, I realized there was a difference compared to a similar toy we have had a couple years. Our previous toy’s design - connected the two loops without any angle - that toy lays flat on the counter. This toy connects the two looped areas at a 90° angle to each other. I like this design. This new angle feels different when tugging for me and the dogs. I can hold the old toy and the new toy and offer to play…at least now, they are choosing this one. I hope my details, thoughts and photos help someone.

Broke Within Moments
My two medium sized dogs played tug of war ONE time and it ripped in half. Not durable at all. Did not hold up well.
