AutoTechEngineer Tip
💡 Professional Practice: For professional injector servicing, it is highly recommended to replace the micro filter whenever injector cleaning or rebuild procedures are performed. This acts as the final line of defense, preventing microscopic tank contaminants from clogging the sensitive internal valve and nozzle components.
Frequently Asked Questions
How do I know which micro filter size (12 mm, 13.8 mm, or 17.8mm) fits my specific injectors?
12 × 6 × 3 mm (Standard MPI): Fits most standard Japanese and worldwide MPI injectors (Denso, Bosch) used in Toyota, Mitsubishi, Nissan, and Honda.
13.8 × 6 × 3 mm (Long Neck / CF104B): Specifically engineered for extended-neck MPI injectors commonly found in Korean vehicles (Hyundai and Kia).
17.8 × 4.6 mm (GDI Slim / TS-11032): Exclusively designed for modern high-pressure Direct Injection (GDI, TSI, TFSI, EcoBoost) systems found heavily in Volkswagen, Audi, and Hyundai/Kia GDI engines (like Tucson and Sportage). These are elongated and ultra-thin to support extreme fuel pressures without causing pressure drops.
What is the most accurate way to verify the filter size before placing an order?
The most reliable method is to use a digital caliper to measure your old basket filter after extraction:
- Measure the total length (12 mm, 13.8 mm, or 17.8mm).
- Measure the outer top lip diameter (6mm for standard/Korean, or 4.6mm for GDI).
Can these micro filters withstand high-frequency ultrasonic cleaning cycles?
Yes, 100%. The body of our filters is molded from premium high-temperature engineering plastic (PA66), and the mesh is made of premium micron-grade nylon. They are fully chemically resistant and structurally reinforced to handle professional injector cleaning solvents and ultrasonic frequencies without tearing or degrading.
Why is it critical to replace the micro filter during every injector service?
The micro filter is the final line of defense for your fuel system. Over time, it traps microscopic rust, tank debris, and fuel contaminants. Reusing an old filter or leaving a clogged one restricts fuel flow, disrupts the spray pattern, and can lead to engine misfires (Missfire) or severe lean-run conditions.
What are the flexible packaging options available for ordering?
We provide total ordering flexibility tailored to your exact needs:
- By Vehicle Setup: Get the exact count for a single-car job with our 4-Pack, 6-Pack, or 8-Pack options.
- By Workshop Bulk: Keep your inventory stocked with our sealed, dust-free trade bags of 50 pieces, or any multiple of 50 (100, 150, 200, etc.).
What makes Auto Tech Engineer products different from standard products?
Standard market parts often look identical but fail under stress because they use cheap materials. At Auto Tech Engineer, we source and validate every component from a strictly engineering perspective—using high-temperature PA66 engineering plastics, premium-micron nylon mesh, and genuine Viton (FKM) rubber for our seals. This ensures absolute geometric precision, 100% resistance to harsh ultrasonic cleaning chemicals, and reliable performance under the intense heat and pressure of modern fuel systems.
