Aftermarket parts can make the most of the solid mid-size build and performance-oriented stock features of any generation, year model and trim level of Nissan Altima. Some repairs may call for the use of replacement parts designed to meet the specifications of the original equipment manufacturer. In other cases, such as with Nissan Altima catalytic converters, you may see gains in terms of power and efficiency when you use vehicle-specific or compatible universal aftermarket parts. This is especially the case if you regularly push the limits of your ride and want to make it more suited to your driving style.
Nissan introduced the Altima in 1992. From the first U13 generation onward, the design of this compact to mid-size sedan has always emphasized acceleration performance and smooth handling. The first generation featured 150 hp KA24DE straight-four DOHC engines. When it comes to Altimas from the 1990s, aftermarket parts can probably achieve an affordable and noticeable improvement in performance and efficiency over many OEM-style components.
Second-generation Altimas featuring a redesigned chassis was launched in 1998 and Nissan continued to manufacture L30 models through 2001. Third-generation models produced from 2001-2006 and fourth-generation models made from 2007-2013 may come with either 2.5L inline-four or 3.5L V6 engines, depending on the submodel and trim package. Starting in 2019, Nissan Altimas began to feature the first production-ready variable compression turbo engine.
In terms of basic standards of performance and efficiency, even late-model Altimas with limited-edition performance trim levels may come up short compared to the same year models and submodels with select aftermarket ignition, engine or exhaust upgrades. Owners of late-model Altimas may still be able to find ways to improve on the performance of a 2.5L PR24DD inline-four or 2.0L KR20DDET turbocharged engine, such as high-quality Nissan Altima brake pads.
Most aftermarket parts manufacturers try to boost performance while reducing exhaust backpressure and emissions. If you need to replace or repair ignition, engine or exhaust components, you may prefer OEM parts designed to provide an exact fit. Modification may be necessary to install aftermarket components and to continue customizing a vehicle that has unique parts.
Aftermarket Nissan Altima catalytic converters may be more effective at reducing emissions than factory components. You may also experience better performance by selecting the best Nissan Altima battery for the climate in your region and your driving habits. There are ways to personalize and upgrade almost every system on this sedan, whether you want to enhance engine power or fuel-efficiency.
Depending on your priorities, you may want to update the ignition or exhaust system on an Altima. If you are interested in raising or lowering the ride height of this vehicle or adding custom body features, aftermarket parts are your best bet. If you also plan on making changes under the hood, be sure to double-check fit measurements and be ready to make some modifications to get the look or unlock the top level of performance possible with one of Nissan’s most popular mid-size sedans.
