Upgrading to an MSD Flying Magnet Crank Kit will deliver the precise and reliable signal that a high performance engine requires. This kit gives you the ability to control timing electronically through a Holley EFI ECU (or other standalone engine management system / ignition controller). At the heart of the kit is the 3-wire Hall-Effect Sensor that is easier to set up, less susceptible to EMI/RFI interference/noise, and less likely to have false signals than other methods (Distributors and VR Magnetic Sensors). In addition, they are less prone to mechanical failure since there are no wear parts. With the included high quality timing pointer and the use of a direct bolt-on, degreed balancer (see below list for recommendations), you'll be able to adjust timing in the precise increments required for your engine. • Coyote 556-173 We recommend using ATI 918047-MSD but will also work with 918047N and 918047NA • LS 8 inch 556-174 Designed to work directly with ATI 917302, 918852, 917264 or 917242 • LS 7.28 inch 556-175 Designed to work directly with ATI 917777, 917211 or 917234 • LS 6.56 inch 556-176 Designed to work directly with ATI 917776 or 917215

Great case, bad magnet.
Size: Iphone 17 Pro Max, Color: Dark Blue
The case itself is very good. It fits well on the phone. It’s not bulky at all and it seems pretty sturdy. The only problem is the magnet in the back is very weak. Besides that, it’s a great buy.

Practical Protection meets everyday elegance
Size: Iphone 15, Color: Black
When it comes to phone cases, functionality often battles design, leaving users to compromise on one or the other. However, the Miracase Magnetic Series Designed for iPhone 15 strikes an impressive balance, making it a standout choice for everyday users. Here’s a deeper dive into this case’s performance, practicality, and aesthetics. Unpacking Military-Grade Protection The first feature that grabs your attention is the military-grade protection claim. Unlike many cases that use the term as a buzzword, Miracase delivers. The corners are reinforced with shock-absorbing material, offering a solid defense against accidental drops. I tested this (intentionally dropping the phone from about waist height), and the iPhone 15 emerged unscathed—a testament to the case's reliability. The anti-scratch back panel further ensures your phone looks pristine, even with daily use. MagSafe Compatibility Done Right This case integrates seamlessly with MagSafe accessories, from chargers to wallets. The magnets are powerful enough to keep your MagSafe charger locked in place but not so strong as to make removing the accessories a struggle. Charging performance remains efficient, with no noticeable slowdowns compared to using the phone without a case. This makes it ideal for users who rely on wireless charging. Dual Screen Protectors: A Value-Added Bonus The inclusion of two screen protectors is a thoughtful touch. These aren’t flimsy add-ons; they are well-crafted with edge-to-edge coverage and excellent clarity. Application is easy with the provided guide frame, minimizing air bubbles—a detail often overlooked by competitors. Anti-Fingerprint and Smudge Resistance One of the standout features is the case’s anti-fingerprint coating. Many cases promise this but fail in practice. After a week of continuous use, the Miracase still looked clean and sleek, even with sweaty hands or frequent handling. The matte finish not only resists smudges but also adds a touch of understated elegance to your device. Slim Profile Meets Grip Security Despite its rugged features, the case maintains a slim profile, sliding easily into pockets. The textured sides provide a secure grip, reducing the chances of accidental drops. This combination of slimness and grip is rare in protective cases and makes the Miracase ideal for on-the-go lifestyles. What Sets It Apart? What truly makes the Miracase Magnetic Series unique is its thoughtful design for real-world use. It doesn’t just protect your phone; it enhances your interaction with it. From its MagSafe efficiency to its smudge-resistant finish, it’s clear that Miracase designed this case with user convenience in mind. Who Is This For? This case is perfect for individuals who want a no-nonsense protective case that doesn’t compromise on style or functionality. It’s particularly suited for professionals, students, and anyone who appreciates the integration of thoughtful design and durable performance. Final Verdict At its price point, the Miracase Magnetic Series Designed for iPhone 15 is an exceptional value. With its military-grade protection, MagSafe compatibility, and added extras like quality screen protectors, it confidently holds its own in a crowded market. Whether you prioritize protection, style, or everyday convenience, this case delivers on all fronts. Rating: 9.5/10 A near-perfect blend of style, durability, and user-focused design.

Great phone case!
Size: iPhone 16e/17e, Color: Black
Perfect protective case for my iPhone 17, without it the phone was too small and easily slipped out of my hand this makes it easier to hold but it’s not too big, it even comes with two screen protectors.
