Bosch Glow Plug 80028 Diesel Engine Replacement Nickel Core

Description

Product Overview

Bosch, a global leader in automotive technology, brings the 80028 glow plug to diesel owners who demand reliability, performance, and longevity. Engineered with a machined exterior, this glow plug features a nickel core that conducts heat efficiently, allowing the plug to reach optimal operating temperature in a fraction of a second. The patented Duraterm technology further accelerates heat buildup, ensuring that even in sub‑zero conditions—down to -18°F—the engine fires up without hesitation. Twin Viton seals protect the internal glow tube from moisture, corrosion, and the constant vibration inherent in diesel powertrains, extending service life well beyond standard OEM replacements. With dimensions of 9.35 x 5.51 x 3.07 inches and a lightweight design of just 0.705 ounces, the plug integrates seamlessly into the engine’s glow plug harness. It carries the OEM part numbers N10140102 through N10140105, guaranteeing a perfect fit for a variety of Volkswagen models, including Beetle (1998‑2003), Golf (1997‑2004), Jetta (1999‑2004), and Passat (1996‑1997). The product is identified by the Global Trade Identification Number 03165143182109 and the manufacturer part number 108628, providing traceability and confidence for service technicians. Tested rigorously in Bosch’s factory facilities, each unit meets or exceeds original equipment specifications, delivering consistent performance across a wide temperature range. Whether you are a professional mechanic, a fleet manager, or a DIY enthusiast, the Bosch 80028 glow plug offers a dependable solution that reduces cold‑start wear, improves fuel efficiency, and enhances overall engine health.

Usage

The 80028 glow plug is designed for diesel engines that operate in demanding environments, from frigid northern winters to high‑altitude regions where air density affects combustion. It excels in passenger cars, light trucks, and commercial vehicles equipped with diesel powerplants that rely on glow plugs for initial ignition. During a typical cold start, the plug’s rapid heat generation reduces the time the engine spends cranking, minimizing stress on the starter motor and battery. This is especially valuable for vehicles that sit idle for extended periods, such as seasonal work trucks or recreational vehicles stored in garages during winter months. The plug also performs admirably in hot climates, where its durable nickel construction resists thermal expansion and maintains stable electrical conductivity. Installation is straightforward: the plug’s OE‑matched terminal—available in pin or screw type depending on the vehicle—fits directly into the existing harness without the need for adapters or extensive rewiring. After replacement, drivers notice smoother engine start‑up, reduced smoke emissions during the first few seconds of operation, and a quieter, more refined idle. Regular maintenance schedules that include inspection of the glow plug can further extend engine life, as the plug helps prevent carbon buildup in the combustion chamber. For fleet operators, the reliability of the Bosch 80028 translates into lower downtime, fewer service calls, and improved vehicle availability, ultimately supporting operational efficiency and cost savings.

FAQ

What vehicles are compatible with the Bosch 80028 glow plug?

The 80028 plug is OE‑matched for several Volkswagen diesel models, including Beetle (1998‑2003), Golf (1997‑2004), Jetta (1999‑2004), and Passat (1996‑1997). Always verify fitment with the vehicle’s VIN or use Bosch’s online fit‑checker to confirm compatibility before purchase.

How does Duraterm technology improve cold‑start performance?

Duraterm technology accelerates the heating process of the glow plug’s core, allowing it to reach the required temperature faster than standard plugs. This rapid heat generation shortens the cranking period, reduces engine wear, and provides a more reliable start in temperatures as low as -18°F.

Can I replace the glow plug myself, or do I need a professional?

While the Bosch 80028 is designed for straightforward installation with OE‑matched terminals, we recommend that individuals with limited mechanical experience consult a qualified technician. Proper torque specifications and handling of the delicate Viton seals are essential to ensure optimal performance and avoid damage to the engine’s glow plug housing.

What warranty does Bosch offer on this glow plug?

Bosch provides a limited warranty that covers manufacturing defects for a specified period after purchase. Details vary by region and retailer, so check the warranty documentation that accompanies the product or contact Bosch customer service for precise information.

How does the nickel core compare to copper‑based glow plugs?

Nickel offers higher resistance to corrosion and better heat retention than copper, especially in harsh environments. This results in a longer service life, more consistent performance, and reduced risk of failure due to thermal fatigue.
