Essential Fluid Checks

Regular fluid checks are the simplest yet most effective way to prevent major issues. Engine Oil: The N55 engine requires specific BMW Longlife-01 (LL-01) approved synthetic oil. Brands like Castrol Edge, Mobil 1, or Liqui Moly are popular choices.

Check the oil level regularly via the iDrive system or dipstick if equipped. Plan for oil changes every 5,000-7,500 miles, even if BMW’s extended intervals suggest longer. Coolant: Use BMW-approved coolant (blue color) mixed with distilled water. Never mix different types of coolant.

Check the coolant reservoir level when the engine is cold. A low level can indicate a leak or a failing water pump.

Brake Fluid: Brake fluid should be flushed every two years. It’s hygroscopic, meaning it absorbs moisture over time, which degrades its performance and can lead to corrosion.

Use DOT4 brake fluid. A pressure bleeder makes this DIY task much easier.

Addressing Known Issues

While generally reliable, the N55 engine and E92 chassis have some common failure points. Being aware of these helps you diagnose problems quickly.

Valve Cover Gasket and Oil Filter Housing Gasket (OFHG): These are very common leak points on the N55. Oil leaks can lead to burning oil smell and contamination of other components.

Replacing these gaskets is a common DIY task. You’ll need a good set of Torx sockets and some patience. Electric Water Pump and Thermostat: The electric water pump is a known failure item, typically failing between 60,000-100,000 miles. It’s often recommended to replace the thermostat simultaneously.

A failing pump will often trigger a check engine light and overheating warnings. This is a job that can be done DIY but is more involved and might require special tools or professional assistance if you’re not comfortable. Charge Pipe Vulnerability: The factory plastic charge pipe (connecting the intercooler to the throttle body) is prone to cracking or bursting under increased boost pressure, especially on tuned cars.

Many owners upgrade to an aftermarket aluminum charge pipe for increased durability and peace of mind.

Basic Performance Upgrades

The 2013 335i is a fantastic platform for performance enhancements. Even basic mods can significantly wake up the N55. Intake: An aftermarket cold air intake can improve throttle response and add a more aggressive induction sound. Expect minimal power gains on its own. Exhaust: A cat-back exhaust system improves exhaust flow and enhances the sound of the inline-six. Look for systems from brands like Akrapovic, Eisenmann, or MagnaFlow.

Tune (ECU Flash or Piggyback): This is the most impactful first modification. A proper engine tune (ECU flash) or piggyback module (like a JB4) can add significant horsepower and torque, often 50-100 hp with stock hardware.

Always research tuners thoroughly and understand the risks involved. Professional tuning is highly recommended to ensure engine longevity.

For DIYers, careful research and quality parts are non-negotiable. Always prioritize reliability and safety alongside power gains.

Power Enhancements

Once you’ve done a basic tune, there are further steps to extract more power from the N55. Piggyback Modules vs. ECU Tunes: Piggyback modules (e.g., Burger Motorsports JB4) intercept sensor signals to trick the ECU into increasing boost. They are generally easy to install/remove and less detectable by dealerships.

ECU tunes (e.g., MHD, Bootmod3) flash new software directly to the engine control unit. They offer more comprehensive control over engine parameters and often yield higher, more consistent power gains. Downpipes: Replacing the restrictive factory catalytic converter downpipes with high-flow or catless versions significantly reduces back pressure. This allows the turbo to spool faster and produce more power, especially in the mid-range.

Be aware of emissions regulations in your area; catless downpipes are often for off-road use only.

Intercoolers: The stock intercooler can become heat-soaked during aggressive driving, leading to power loss. An upgraded, larger intercooler improves charge air cooling, maintaining consistent power output.

This is a highly recommended upgrade for any tuned 335i.

Handling & Braking Upgrades

It’s crucial to upgrade handling and braking to match increased power. A faster car needs to stop and turn better.

Coilovers & Suspension Kits: Aftermarket coilovers allow for adjustable ride height, damping, and sometimes camber. They can dramatically improve handling, reducing body roll and sharpening turn-in.

Brands like Bilstein, KW, and Ohlins offer excellent options for the E92 chassis. For DIY coilover installation, ensure the car is safely on jack stands and follow torque specs carefully. Sway Bars: Upgraded front and rear sway bars (anti-roll bars) further reduce body roll. This makes the car feel flatter and more composed during cornering.

Often, a thicker rear sway bar is a popular first step for track-focused drivers. Big Brake Kits (BBK): For serious track use or significant power upgrades, a Big Brake Kit (BBK) from brands like Brembo or StopTech is an excellent investment. These kits feature larger rotors and multi-piston calipers, offering superior stopping power and heat management.

Remember that a BBK might require larger wheels to clear the calipers.

Safety First with Modifications

Modifying your 335i can be rewarding, but safety should always be your top priority. Importance of Quality Parts: Always invest in reputable, high-quality aftermarket parts. Cheap parts can fail prematurely, leading to costly repairs or dangerous situations. Professional Installation for Critical Components: While many mods are DIY-friendly, critical components like brakes, suspension, or complex engine internals should be installed by experienced professionals if you’re unsure. Incorrect installation can lead to severe safety hazards.

Understanding Legal Implications: Be aware of local and state laws regarding vehicle modifications, especially concerning emissions and noise. Catless downpipes, for example, are illegal for street use in many areas.

Always ensure your vehicle remains roadworthy and compliant.
