Installed it with a bung extension. Working as it should. Let’s see how long it lasts Review: works as replacement for aem x series wideband - the sensor for one of my aem x series widebands went bad & would peg lean at all times. the innovate sensor was the fastest available one so i took a chance figuring it would work and it works just as well as the original aem sensor. the cable on the innovate may be a little longer than the aem one so thats a plus for anyone looking at this as a replacement too ## Features - Package Dimensions: 4 L x 4 H x 1 W (inches) - Package Weight : 0.5 pounds - Country of Origin : United States - Fit type: Vehicle Specific - Compatible with the LM-2, LC-2, and MTX-L, SCG-1, DLG-1, PSB-1, and PSN-1 gauges - Verify which sensor (4.2 or 4.9) your system needs - Monitors oxygen presence in fuel emissions - Wideband O2 compatible with leaded, unleaded, diesel, and E85 fuels ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B013UG0MUS | | Best Sellers Rank | #213,120 in Automotive ( See Top 100 in Automotive ) #856 in Automotive Replacement Oxygen Sensors | | Brand | Innovate Motorsports | | Brand Name | Innovate Motorsports | | Customer Reviews | 4.1 out of 5 stars 310 Reviews | | Global Trade Identification Number | 00856428038886 | | Included Components | Oxygen Sensors | | Item Dimensions | 1 x 4 x 1 inches | | Item Type Name | Oxygen Sensors | | Item Weight | 150 Grams | | Item dimensions L x W x H | 1 x 4 x 1 inches | | Manufacturer | Innovate Motorsports | | Material | Metal | | Material Type | Metal | | Measurement Accuracy | 0.1 AFR | | Measuring Range | [0 AFR ± 0,1 AFR] | | Model | 3888 | | Mounting Type | Flange Mount | | Output Type | Analogue | | Specific Uses For Product | Automotive | | Style | Modern | | Style Name | Modern | | UPC | 856428038886 077063279247 | | Upper Temperature Rating | 125 Degrees Celsius | | Warranty Description | No warranty on O2 sensor, wear item | ## Product Details - **Brand:** Innovate Motorsports - **Item Weight:** 150 Grams - **Item dimensions L x W x H:** 1 x 4 x 1 inches - **Material:** Metal - **Style:** Modern ## Images ![3888 Replacement Oxygen Sensor - Image 1](https://m.media-amazon.com/images/I/51nUpGCPBQL.jpg) ## Questions & Answers **Q: What's the bosch p/n on this sensor? i ordered a 17025 sensor for my lc-2, but the connector wasn't compatible.** A: 17025 is the correct Bosch part number for the wideband O2 sensor. **Q: Is there a warrantee on this sensor?
