HP EFI Universal MPI Retrofit Kit, 4500 carburetor style intake manifolds

Overview
Do you have a Mopar, Ford or other type engine you want to install multi-port fuel injection on? No, problem, the Holley HP universal MPI retrofit EFI kits are designed to be used with any V-8 intake manifold. The kit comes with injector bungs and un-machined fuel rails so you can modify to fit any single plane 4bbl intake manifold. The HP universal retrofit kits also come with the necessary wiring, ECU, sensors and throttle body. Just select the fuel pump and injectors of choice and you are off and running.

The following sensors are included: TPS - IAC - MAP - CTS - MAT - Wideband O2 ECU is certified to ISO 8846, SAE J1171 United States Coast Guard Requirements for Ignition Protection Fire Resistance. Holley HP EFI systems are equipped with 4 programmable inputs and 4 programmable outputs that are ideal for most vehicles with a single power adder. This feature allows the user to configure the system to support a wide range of controls including boost control, progressive nitrous, water/meth injection, speed inputs, fuel pump control, AC inputs, timing retard inputs and various other uses. When selecting an ECU, users need to ensure their planned controls can be run with the 4 inputs and 4 outputs as certain combinations may use more I/Os than are available. If more I/Os are required, users should choose the Dominator VMS.

All Five Toys Are Mine Now — A Review by Patches the Pomeranian
Color: Pink, Color: Pink
⭐ “Hi, I’m Patches, and These Toys Are All Mine Now” — A Review by a Very Busy Pomeranian ⭐ Hello, my name is Patches, and I am what the humans call a “toy enthusiast.” What that really means is: if a toy enters this house, it belongs to me immediately, no questions asked. The Pack Leader brought home this 5‑Pack Puppy Chew Toy Set — a pea pod, a wing‑shaped chew, and three cute fabric‑tied toys. Five toys. Five opportunities for greatness. Five items for my personal collection. He tried to hand one toy to each of us like we’re participating in some kind of polite sharing ceremony. Very sweet. Very unrealistic. The moment my sisters glanced away for a single second, I activated my elite move: The Pomeranian Slide‑In‑and‑Snatch. I took my toy. I took their toys. I took the toys on the floor. I would’ve taken the mail if it looked interesting. Now I have all five toys, and my sisters have… well… the joy of watching me parade around with them like a tiny fluffy champion. 🦴 My Professional Toy Review Pea pod: Chews beautifully and looks adorable when I carry it around like a prize. Wing bone: Excellent for dramatic chewing sessions. Fabric toys: Perfect for shaking, tossing, and showing off. They don’t squeak, they don’t bounce — and honestly, that’s perfect. I enjoy a quiet chew while plotting my next toy acquisition. 😬 Teething & Dental Stuff The humans say these toys help clean teeth and massage gums. I don’t know about all that. I just know they feel good to chew and keep me busy while my sisters stare at me in disbelief. 🎁 Final Thoughts If your puppy enjoys chewing, collecting, or claiming ownership of everything within paw‑reach, this set is a fantastic choice. 5/5 stars. Would absolutely claim again.

Anya loves her new baby toys
Color: Pink, Color: Pink
This review is for the YZHZIIR 5 Pack Puppy Chew Soft Rubber Dog Toys. As you can see in my photos, my Borzoi “puppy” is quite large. I knew these toys are not meant for extra large breed puppies, but for some odd reason, ours loves little tiny toys. She usually will just carry them around in her mouth and will gently play with them. That being said, she will have these baby toys in her “supervised only” drawer. This order came with 5 toys per pack, as stated on line. They look exactly like what you see, and it even specifies the sizes. I think if you have a toy breed, these are suitable since they’re safe to chew (not ingest). They’re BPA and phthalates free, made of natural rubber, so I’m not concerned about her developing a third eye or a lump somewhere on her body. My puppies are the apple of my eye, so they are supervised whilst playing with small, easy to tear apart toys or goodies that may have a choking hazard. So my recommendation is that unless you are keeping a close eye on them, stick to giving these to toy breeds with tiny teeth, or very young puppies who could barely chomp down on soft puppy food. The price is unbeatable. For 5 toys, you pay only $9.99!

Made Puppy Sick!
Color: Blue, Color: Blue
Fell apart fast, my pup tore pieces off and it made him sick. I really wanted these to work because they are so cute as "baby" toys for puppies and the listing promises “durable & chew‑resistant” toys that can stand up to sharp puppy teeth and even says they’re safe for extended chewing with no health risks because they’re made from “100% natural rubber” with no BPA or harmful chemicals. Unfortunately, that wasn’t my experience at all. My pup had these for only a short time before he chewed pieces off, and the toys started breaking apart way faster than expected. After swallowing some of the pieces, he ended up sick to his stomach, which meant the toys had to go straight in the trash. He was up all night with diarrhea and vomiting, at first, I didn't put it together until I found blue pieces of the rubber toy in his vomit.

good toys but better for gentle / non aggressive teethers
Color: Blue
cute but not very durable. better for dogs who are not aggressive chewers even though they are young pups. when they are broken apart by teeth, the pieces are at least clean cuts. no big concerns of ingestion

Cute set for my 2-1/2 pound chihuahua puppy, and this set would also make a great gift
Color: Pink, Color: Pink
First off, I like how each piece is individually wrapped and then placed all together in a plastic bag. While it's not in a gift box, I feel like this would still make a really cute gift (that shows up in good shape, too.) For the current price of under ten bucks, this feels like a really great value for five cute toys. My chihuahua puppy is only 2-1/2 pounds, so some of these are a bit larger for her, but that's to be expected at her tiny size, and it doesn't stop her from enjoying them. These feel really sturdy to me for smaller dogs to chew on. I personally love the added "ribbons" because I think they're adorable and because my dog loves things like that. They really get her to engage with toys even more. while also giving me another way to interact with them more as I play with her. I could see how those fabric pieces may wear down over time for a larger dog, but I think it depends on how much a dog focuses on chewing on those pieces. Fortunately, the plastic toys will still be cute without those fabric pieces if anything happens to them. Unfortunately, the plastic pieces have a very slight odor. I'm super sensitive to smells, so you may not notice it at all. It's certainly not as bad as so many other plastic items, and it came right off when I washed it in dish soap (which I would do before giving these to my pup anyways.) I hope your small dog enjoys these as much as we do, and I hope you find this review helpful!
