PRODUCT DETAILS ▾
RallySport Direct is proud to offer the automotive enthusiast with a quality selection of AutoMeter Gauges. AutoMeter has been seasoned in the sport compact community for decades and was one of the first companies to offer aftermarket gauges for race and street applications. Today, AutoMeter continues to design, build, and engineer quality gauges suitable for all makes and models for all different types of use. Be sure to choose the right gauge to suit your vehicle.
On this page, you are looking at the AutoMeter 2-1/16" Elite Wideband Pro Air/Fuel Ratio Gauge. Wideband gauges are often used as tools for tuners on turbocharged and modified naturally aspirated engines to make sure that the tune is within the strike zone under throttle. The job of the wideband is to indicate the driver whether if your vehicle is running lean or rich to avoid catastrophic engine failure. If you have a vehicle with mild or moderate bolt-ons, a wideband gauge is a must as things like weather, fuel type, and elevation can change how your vehicle runs.
Here are some key features:
- Gauge kit includes custom tuned .1 AFR Resolution Bosch LSU4.2 Sensor, 8ft. wiring harness, 304 stainless steel weld-in bung, mounting hardware, and detailed instructions for installation
- 0-5V data output feed for ECU, data acquisition unit, or Laptop tuning
- User programmable range for Rich/Stoic/Lean conditions
- Peak recall/memory
- 10:1 to 20:1 AFR Range for Gasoline Applications
- 12 and 16 volt compatible, compatible with nearly every street car or race car electrical system
- User Programmable Warning Function
- Display data in Lambda or numerical A/F ratio
WHY WE CARRY THIS ▾
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT ▾
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
