NVLMBL Air Filter and Spark Plug Kit for Troy-Bilt TB110 TB115 TB200 TB230 TB330 TB370 — 2 Pleated Filters + 1 Spark Plug, OEM-fit

This kit supplies essential airflow filtration and reliable ignition components so your Briggs & Stratton-based Troy-Bilt mower runs cleaner and starts more dependably. The pair of pleated paper filters traps dust and debris before they reach the carburetor, while the single replacement spark plug restores consistent combustion. Every component is sized for direct fit with the listed Troy-Bilt models and compatible B&S engine families, making this a straightforward tune-up option.

How does the NVLMBL air filter protect my mower engine?

The pleated filter media increases surface area to capture more particles without restricting airflow, reducing abrasive wear on internal parts. Cleaner intake air helps preserve carburetor and cylinder condition and maintains steady performance under load.

• Pleated paper element for increased particle capture
• Rubber-molded frame for a tight seal and vibration resistance
• Prevents dust and grass debris from entering combustion chamber
• Designed to match OEM dimensions for correct airflow balance

Will the spark plug in this kit improve starting and throttle response?

Yes — installing a fresh, correctly gapped spark plug restores consistent ignition timing and stronger sparks across the RPM range. That generally yields more reliable starting, steadier idling and crisper throttle response compared with a fouled or aged plug.

• Proper fit and thread length for listed Troy-Bilt engines
• Factory-recommended gap for dependable combustion
• Easy hand-start installation followed by a 1/4-turn wrench snug
• Complements the cleaner intake air from new filters

How simple is it to replace these parts on my mower?

Replacement is designed to be homeowner-friendly: the air filter removes from its housing without special tools, and the spark plug can be threaded in by hand before a final quarter-turn with a spark-plug wrench. Basic hand tools and a few minutes are all that’s needed for a routine tune-up.

• Air filters slide in/out of the air box for quick service
• Spark plug installs by hand then tightened 1/4 turn with wrench
• No carburetor disassembly or engine modifications required
• Includes two filters for front-and-back or staged replacements
