Air Filters
While modern automotive technology has largely shifted to electronic fuel injection (EFI) systems for their efficiency and performance benefits, the carburettor remains a celebrated component among classic and performance vehicle enthusiasts. This mechanical air valve, pivotal in the history of automotive development, regulates the air-to-fuel ratio, delivering the optimal mix to the internal combustion chambers. In specific contexts, particularly in classic cars and certain performance setups, the simplicity and adjustability of carburettors make them a preferred choice.

The carburettor's primary function is to mix air and fuel in the correct ratio for combustion. As the piston moves down during the intake stroke, it creates a vacuum that draws air and fuel into the combustion chamber. The positioning of the carburettor's butterfly valves controls this ratio and, in turn, the engine's RPM (Revolutions Per Minute).
However, the carburettor's role doesn't end there. It also ensures that the engine doesn't run too rich (too much fuel) or too lean (too much air). Both scenarios can harm the engine, with the latter being particularly damaging and potentially leading to costly repairs. An engine running too rich or too lean will also suffer in terms of efficiency and power delivery.
During the 1980s, advancements in technology led to a shift away from mechanical carburettors to fuel injection systems. These systems deliver fuel either directly to the combustion chamber (direct injection) or combine fuel with air prior to the intake stroke (indirect injection).
While fuel injection systems are generally more suited to road use due to their superior fuel efficiency and emissions control, mechanical carburettors still hold their own, particularly in track use. The simplicity and reliability of carburettors, coupled with their lack of drain on the engine, make them a favoured choice for many performance and racing enthusiasts.
When selecting a carburettor, it's essential to consider your vehicle's specific needs and your driving habits. Here are a few factors to consider:
Whether you're a seasoned racer or a car enthusiast looking to enhance your vehicle's performance, a high-quality carburettor can make a significant difference. By delivering the optimal air-fuel mix to your engine, a well-chosen carburettor can improve power delivery, increase fuel efficiency, and enhance overall engine performance.

Very few new production cars come with carburetors anymore. Modern vehicles almost exclusively use fuel injection systems for the reasons we discussed – efficiency, emissions, and performance.
However, plenty of classic and vintage cars on the road *still* run carburetors. Maintaining these carbs is a specialized skill! There’s a thriving aftermarket for carburetor parts and rebuild kits to keep those older machines running smoothly.
You might also find carburetors in certain niche applications like off-road racing or custom builds where simplicity and mechanical control are prioritized over ultimate efficiency.
You’ll find carburetors mostly on older vehicles, generally pre-1980s. Classic American muscle cars like the Ford Mustang, Chevrolet Camaro, and Dodge Charger often came with carburetors.
Japanese bikes from the 70s and 80s also heavily featured carbs. Beyond that, you’ll see them in some small engines – lawnmowers, generators, and older motorcycles are common examples.
Some performance enthusiasts still use carburetors on modified engines even today because they offer a simpler tuning experience for maximizing power, but these are exceptions rather than the rule.
Carburetors aren’t “bad” technology – they just couldn't keep up with modern demands. The biggest issue is precision. Carburetors mechanically meter fuel, and that’s hard to do perfectly in all conditions.
Fuel injection systems, which took over starting in the 80s, use electronic sensors and a computer (ECU) to precisely control how much fuel enters each cylinder. This means better fuel economy, lower emissions, and more consistent performance—especially in varying temperatures and altitudes.
Let's be honest: modern regulations around pollution are tough. Fuel injection makes it far easier for cars to meet those standards than a carburetor ever could.
A carburetor’s job is pretty simple: it mixes air and fuel in the right proportions for your engine to burn. Think of it like a chef carefully combining ingredients before cooking.
As your engine sucks air in during the intake stroke, the carb uses vacuum to draw fuel into that airstream. It then atomizes – breaks down the fuel into tiny droplets – so it mixes thoroughly with the air. This mixture is what gets ignited in the cylinders to create power.
Older engines relied heavily on carbs for this process. While modern cars use fuel injection, understanding carburetors is still key for classic car enthusiasts and racers who appreciate their simplicity and tuning potential.
