Especially effective on turbocharged applications, these polished, universal items of loveliness are designed to trap the oil vapour vented from the engine’s crankcase before the car dumps it all back to be burnt off via the inlet.
In other words, you get a cleaner airflow, quite possibly more power and another shiny trinket to impress the world every time you open the bonnet.
TIG welded and finished with a range of motorsport-style AN fittings (or traditional push-on hose fi ttings), these 1-litre tanks are a hell of a lot of top-end kit for around the 50-quid mark.
Priced from £50
