The BOIGEVIS High Quality Fuel Injector Repair Kit (OE No. 03H198149 / 03H 198 149) is a lower injector seal-and-clip service set for Volkswagen and Audi 3.2L / 3.6L VR6 FSI engines, covering cylinders 2, 4 and 6 (paired with 03H198149A for 1, 3, 5).
It fits Audi Q7 3.6 V6 (2007–2010), VW Atlas / Atlas Cross Sport 3.6L V6, CC VR6 3.6, Passat B6/B7 3.6 V6, Touareg 3.6 V6 and related Porsche Cayenne 3.2 V6 applications sharing the VAG 3.2/3.6 FSI injector (03H906036A / 03H906036F).
Each kit services one injector and includes heat- and fuel-resistant O-rings plus the retaining clip, restoring the seal between injector and intake manifold. Replacing these during rail removal, manifold cleaning or injector swap prevents fuel vapor leaks, raw-fuel smell, rough idle, lean misfire and P0171/P0300-series faults caused by hardened original seals.
BOIGEVIS moulds the rings to OEM cross-section and shore hardness, leak-checks batches and cross-verifies against 03H198149A, 95511091000 and Elring references before packing. Aimed at VW-Audi specialists, intake-manifold overhaulers and export distributors, it delivers genuine-level sealing at aftermarket cost, with BOIGEVIS warranty and container shipping from its Guangzhou warehouse. Never reuse old O-rings on reinstall.
