Nissan Altima owners, if you need to replace that front passenger side fender liner, this FitParts version is exactly what you're looking for. Specifically designed for 2019-2020 Altima sedans, this is a direct fit replacement that matches the original factory part perfectly. It's brand new and comes factory sealed, made from durable plastic that meets or exceeds DOT and SAE compliance standards. The installation is seriously straightforward - no difficult modifications or special tools needed. It just bolts right into place like the original. This replaces OEM part numbers NI1249166 and 638406CA0A, so you know it's the correct fit for your vehicle. The quality is excellent - it's not some flimsy aftermarket part that'll break in six months. FitParts stands behind this with a 1-year warranty too. If your original fender liner got damaged from road debris, weather, or just general wear and tear, this replacement will restore that factory protection for your engine compartment. It helps keep moisture, dirt, and road spray from getting where it shouldn't. The placement is specifically for the front right passenger side, so make sure that's what you need before ordering. For anyone who's dealt with a flapping or missing fender liner, you know how annoying that noise can be - this fixes that problem completely. The price is way better than going through the dealership, and the quality is genuinely comparable to OEM. If you're comfortable with basic car maintenance, this is a job you can probably handle in your driveway with basic tools. Your Altima will be back to its quiet, protected self in no time!
