Zexel 105148-1121 Diesel Fuel Injector – Mechanical Precision For Nissan TD42 / TD27 Work Engines

For many classic Nissan diesels, reliability isn't a marketing word-it's a daily requirement. Engines like TD42 (4.2L) and TD27 (2.7L) earned their reputation by running hard in harsh conditions, but even the toughest mechanical engine depends on one detail: consistent fuel atomization. The Zexel 105148-1121 injector is a widely used replacement designed for these mechanical injection systems, bringing back clean spray, stable idle, and confident pull under load-without the complexity of common rail electronics.  

This product is commonly sold as a direct-fit diesel fuel injector for Nissan platforms, and many suppliers list it either individually or as a complete engine set (often a set of six for TD42 applications

 

 

Mechanical injectors don't "self-correct" the way modern ECUs do. As nozzle wear increases, fuel delivery can become less precise, leading to poor combustion and the familiar symptoms owners search for online:

★ longer cranking and harder starts
★ rough idle or "shaking" at low RPM
★ black smoke under acceleration
★ weaker throttle response, especially uphill

Replacing tired injectors with a correctly matched 105148-1121 set helps restore the spray pattern that these engines were designed around-often improving drivability immediately after proper installation and tuning.

 

 

Online fitment listings commonly associate 105148-1121 with Nissan diesel engines including TD42, TD27, and related families such as TD23/TD25 depending on market and model. 

Commonly listed vehicle coverage includes:

Nissan Patrol (TD42 4.2L) cdsa. 

Nissan Navara / Pick-Up (D21) (TD25/TD27 in many listings)  

Nissan Pathfinder / Terrano (TD27 platforms commonly referenced) 

Nissan Cabstar (TD25 in multiple fitment entries)  

Ford Maverick (often cross-listed with TD42/TD27 injector sets) cdsa. 

Many suppliers describe the coverage broadly as TD42 4.2L and TD27 2.7L spanning 1986–2007 for popular Patrol/Navara/Pathfinder/Terrano/Maverick applications.  

Because mechanical diesel variations exist by year and market, your product page should encourage customers to confirm by engine code and injector/OE number, not vehicle name alone.

 

 

To capture high-intent traffic, include the common number cluster that appears in catalogs and workshop invoices. 105148-1121 is frequently shown alongside Nissan OEM and related Zexel numbers such as:

Nissan OE numbers like 16600-43G01 / 16600-43G03 / 16600-46G02 (commonly used when quoting TD42 injectors) cairnsdiesel 

Alternate Zexel references often listed in the same family: 105078-0050 / 105078-0050B, plus references like 9430613538 and 9430610405 in some supplier systems cairnsdiesel. 

Some marketplace listings also show 16600-43G02 / 1660043G02 / 1660043G03 as related OE identifiers  

These references help your independent site rank for searches like "16600-43G03 injector," "105078-0050 vs 105148-1121," and "TD42 injector set."

 

 

✔ Mechanical-system correct: suppliers clearly describe this injector family as mechanical (non-common rail), which is exactly what TD42/TD27 owners need. 
✔ Set-friendly: many sellers offer complete sets (especially for TD42 6-cylinder engines), which is ideal for balanced fueling across cylinders.  
✔ Built for service life: suppliers position genuine Zexel units as OE-standard components for long-term daily use on TD42/TD42T platforms.

 

 

• Match by number first: confirm 105148-1121 (or OE equivalents like 16600-43G03) before ordering 
• Replace as a set when possible: mixed old/new injectors can create uneven combustion.
• Use professional calibration: pop pressure and spray pattern checks are recommended during install on mechanical systems.
• Clean fuel practices matter: new injectors won't last if filtration and fuel quality are ignored.
