Bosch Style Line 2 in Triple Gauge Kit - Clean Retro Look

In this review of the Bosch Style Line 2 in Triple Gauge Kit the bottom line is simple: it is a compact, retro-styled gauge cluster for 12 volt negative ground vehicles that delivers clear readouts and easy installation for most hobbyists and restorers. The kit bundles a 2 in oil/water temperature gauge, a 2 in electrical voltmeter and a 2 in mechanical oil pressure gauge into a removable black mounting panel, and includes 72 in high temperature tubing, fittings, mounting hardware and 12 volt internal lighting. For anyone restoring a classic dash or adding a tidy secondary cluster the biggest reason to buy is the combination of Bosch engineering and a clean black-dial aesthetic that keeps wiring and plumbing straightforward.

Key Features

• Triple gauge set: Combines Oil/Water Temperature, Electrical Voltmeter and Mechanical Oil Pressure into one compact 2 in cluster for a tidy dash install.
• Black dial and bezel: The black dial face with black bezel and bright pointer improves legibility and matches many vintage or modern dashboard finishes.
• Included tubing and fittings: Ships with 72 in of high temperature nylon tubing and both 1/8 in and 1/4 in NPT thread fittings to simplify plumbing to the oil and temperature sensors.
• Integrated lighting: Built-in 12 volt internal lighting lets the gauges be readable at night without separate lamps.
• Mounting hardware and panel: The removable black mounting panel and included hardware make panel cutout and attachment straightforward for most installers.

Who It's For

The Bosch Style Line triple gauge kit suits car restorers, custom builders and DIY enthusiasts who want a compact instrument cluster with a retro look and straightforward installation. Because the gauges are 2 in and designed for a 2-1/16 in opening, it is especially useful where dash space is limited or when adding a small supplemental pod.

It is not intended for vehicles with electrical systems other than 12 volt negative ground, nor for users who need fully digital or multi-function displays. Buyers who need ultra-robust industrial duty or telemetry-grade accuracy for race applications should evaluate purpose-built racing gauges instead.

Pros & Cons

Pros

• Attractive, easy-to-read black dials and bright pointers give a clean, classic look.
• Complete kit includes tubing, fittings, mounting hardware and 12 volt lighting for a mostly plug-and-play install.
• Compact 2 in size lets it fit tight locations and a removable mounting panel simplifies fitting.
• Bosch engineering provides a level of build quality and component compatibility expected for replacement automotive gauges.

Cons

• Several users report concerns about the longevity of the mechanical oil pressure gauge and occasional leaking at fittings, so durability may vary.
• Only compatible with 12 volt negative ground systems, limiting use in other electrical setups.

Specifications

Our Verdict

The Bosch Style Line 2 in Triple Gauge Kit is a sensible value for restorers and DIY installers who want classic styling, compact size and an included hardware kit that reduces installation time. It delivers clear readouts and useful components, though buyers should be aware of occasional reports of oil pressure gauge issues. Overall it is a good choice for street use and period-correct builds where Bosch quality and a neat, simple cluster are priorities.

Frequently Asked Questions

Will this kit work on a 24 volt system?
No, the gauges and internal lighting are intended only for 12 volt negative ground electrical systems.

Does the kit include fittings and tubing for the pressure gauge?
Yes, the kit includes 72 in of high temperature nylon tubing and both 1/8 in and 1/4 in NPT thread fittings to connect the mechanical oil pressure and temperature sensors.

Are the gauges illuminated for night driving?
Yes, the cluster has 12 volt internal lighting so the dials are visible at night when wired to the vehicle lighting circuit.
