1999 Porsche Boxster Rear Tail Light Cover Replacement Parts: What to Know Before Buying

If you own a 1999 Porsche Boxster, you know that even a small cosmetic issue like a cracked or faded rear tail light cover can detract from the car’s classic lines. Replacing that cover is a straightforward fix, but choosing the right part requires some knowledge. This article walks you through the options—OEM, OEM-equivalent, and aftermarket—along with material considerations, fitment notes, and installation basics. By the end, you’ll know exactly what to look for when shopping for a 1999 Porsche Boxster rear tail light cover replacement part.

Understanding the Role of the Tail Light Cover

The rear tail light cover on a 1999 Boxster does more than just look good. It protects the bulbs and housing from moisture, dirt, and road debris. A compromised cover can lead to water ingress, corroded contacts, and eventual electrical failure. Given the age of these cars, the original plastic covers often become cloudy, cracked, or yellowed due to UV exposure. Replacing just the cover—rather than the entire assembly—saves money and keeps the original housing intact.

OEM vs Aftermarket: Key Differences

OEM (Original Equipment Manufacturer) Parts

OEM replacement covers are made by the same supplier that provided the part to Porsche. For the 1999 Boxster, the original supplier was typically Hella or a similar Tier-1 automotive lighting manufacturer. OEM parts offer guaranteed fitment, material quality, and color matching. They are the safest choice if you want the exact same look and durability as the factory part. The downside is cost: OEM covers can be two to three times more expensive than aftermarket options.

OEM-Equivalent (OE) Parts

Some manufacturers produce covers that match OEM specifications exactly but are sold under their own brand. These are often made in the same factories as OEM parts but without the Porsche logo. OE parts are a middle ground: they provide similar quality and fit at a lower price. Brands like DEPO or TYC are common for European lighting. Always check that the OE part is specifically listed for the 1999 Boxster—some are designed for multiple models and may require modification.

Aftermarket Parts

The aftermarket offers a wider range of prices and materials, including polycarbonate or acrylic covers. Some are direct-fit, while others are universal and require trimming. Aftermarket covers can be cheaper, but quality varies. Inexpensive covers may warp, cloud quickly, or have poor sealing. If you go aftermarket, stick with brands known for lighting parts, like Anzo or Spyder, and read the product description carefully for material and fitment notes.

Material Matters: What to Look For

Most OEM covers are made from injection-molded polycarbonate (PC) with a UV-stabilized coating. Polycarbonate is impact-resistant and lightweight. Cheaper aftermarket covers often use acrylic (PMMA), which is more brittle and prone to cracking. If longevity is important, opt for polycarbonate. Some higher-end aftermarket covers use a UV-resistant coating to prevent yellowing—check for that in the description.

Fitment Considerations for a 1999 Boxster

The 1999 Boxster (986 generation) has a specific tail light cover design. The rear lens is a single piece that covers the brake, tail, and turn signal bulbs. It attaches to the housing with screws or clips. When buying a replacement cover, ensure it is explicitly listed for the 1999 model year. Some covers fit 1997-2001 but may have minor variations in the lens pattern or mounting points. Also, note whether the cover comes with a new gasket or seal. A worn gasket can allow moisture entry, so it’s wise to replace it at the same time.

Installation Tips for DIYers

Replacing the tail light cover is a beginner-friendly job. You’ll need a screwdriver (usually Torx or Phillips) and possibly a trim removal tool. Steps:

1. Open the rear trunk and remove the interior panel to access the back of the tail light housing.
2. Unplug the wiring connector and remove any mounting nuts or screws holding the housing to the body.
3. Gently pull the housing out. On some models, you may need to remove the entire assembly first, then separate the cover from the housing.
4. Remove the old cover by unscrewing or unclipping it. Transfer any rubber gaskets or seals from the old cover if the new one doesn’t include them.
5. Attach the new cover, ensuring a tight seal. Reinstall the housing and reconnect the wiring.

Test all functions (brake, tail, turn signal) before closing everything up. If the lights don’t work, check the bulb contacts and connections—the housing may be slightly misaligned.

Common Questions About 1999 Boxster Tail Light Covers

Can I replace just the lens, or do I need the whole assembly?

Yes, many suppliers sell the lens/cover separately. However, if the housing is damaged or the mounting tabs are broken, you may need the full assembly. Check the condition of your housing first.

Are LED covers available for the 1999 Boxster?

Some aftermarket covers are designed for LED bulbs, but they often require additional resistors to prevent hyper-flash. If you want an LED look, consider replacing the entire assembly with a plug-and-play unit made for the 986 chassis.

How do I know if a cover is genuine or counterfeit?

Authentic OEM and OE parts have clear part numbers stamped on the back or edge. Compare to known listings from Porsche or reputable parts retailers. Counterfeit covers may have blurred stampings or poorly finished edges.

Cost Comparison

Expect to pay:

• OEM cover: $120–$250
• OEM-equivalent: $60–$120
• Aftermarket cover: $30–$80

Prices vary by seller and whether the part includes a gasket. Keep in mind that very cheap covers (under $30) often come from no-name brands with little quality control.

Final Recommendation

For a 1999 Porsche Boxster, the smartest choice is an OEM-equivalent cover from a known brand like DEPO or TYC. You get near-OEM quality at a lower price, and the fitment is reliable. If you want the absolute best match in color and texture, pay the premium for an OEM part from Hella or a Porsche dealer. Avoid the cheapest aftermarket options unless you’re willing to accept potential fit issues and shorter lifespan. Always buy from a reputable auto parts retailer that accepts returns, and double-check that the cover is designed for the 986 chassis. With the right part, your Boxster will look sharp and stay dry inside for years to come.
