There are a full set of illustrated instructions inside the lid of every PowerBoost can

When applying PowerBoost please read the instructions carefully to be sure of getting the very best results. This 600 ml can provides a full first time treatment for engines with over 20,000 miles (see 5 below) or two treatments for new or previously treated cars after 12,000 miles (see 6 below).This may well be one of the most effective maintenance operations you undertake on your engine so make sure you apply the PowerBoost in precisely the correct manner.


The PowerBoost foam is applied to the air intake of an engine running at between 2,000 and 3,000 revs so the procedure requires two people – one to maintain engine revs and one to apply the foam.

1. Read the instruction leaflet contained in the PowerBoost cap to establish where to inject the PowerBoost foam.

a) For carburettor cars – remove the air filter housing and inject PowerBoost straight into the carburettor. If this

is not possible remove just the air filter and inject into the air intake.

b) For petrol injected* cars PowerBoost must be injected downstream of the Air Mass Meter. If you are in any doubt consult a professional mechanic.

2. Warm up the engine to operating temperature.

3. Shake can and align the nozzle with the black dot – this ensures that when the can is tipped the foam still flows at the correct rate

and exhausts the can fully. Try to keep the can as upright as possible (see 4. below). If you do not do this there will be a residue left in the can.

4. Insert the extension tube – this is often necessary to keep the can as upright as possible or when inserting foam in an awkward position. Two tubes are provided in case of loss or damage or for two 12,000 mile applications. The tube affects the time taken to exhaust the can and should always be used.

5. In the case of a first time application – untreated engines of over 20,000 miles:

a) Apply foam into air intake or manifold with the engine running at a steady 2,500 – 3,000 rpm (2,000 – 2500 for Diesels) for 2 (two) minutes.

b) Leave engine idling for 3 (three) minutes then repeat a) above.

c) Repeat a) and b) until foam is exhausted – minimum 8 minutes treatment per can.

d) Drive the vehicle for ten minutes using, safely and where possible, the full rev range through the gears to complete the decoking process.

6. Subsequent treatments (per 12,000 miles):

a) In the case of pre-treated cars and those that have completed 12,000 miles follow 5a) and 5b) above twice – a total foam application of 4 (four) minutes and then 5d).

Important note for EFI cars


7833bd34With Electronic Fuel Injected (EFI) cars the chemicals in PowerBoost can affect the sensors in the Air Mass Meters in some cars; specifically of “Hot Wire” Electronic Petrol Injection systems. As a general rule therefore always apply the PowerBoost Foam downstream (engine side) of the Air Mass Meter (AMM).

Here are some illustrated examples showing the Air Mass Meter circled (they are also reproduced in the instruction leaflet contained in the lid of every can of PowerBoost); The AMM is invariably next to the air box containing the air filter. The airflow is from this box, across the air mass meter and towards the throttle body.6755fc74

You can undo any of the clips that hold the flexible pipe of the induction system downstream of the air-box and apply the foam into this pipe quite easily while the engine is running – see instructions.

Locating the Air Mass meter is quite straightforward as can be seen from these illustrations; it is the first electronic sensor next to the air-box and can be identified by the electrical wires coming out of it and leading to the ECU. Simply apply the foam near the engine and away from the AMM.

In the case of Turbo or Supercharged engines apply directly into the charger wherever possible. This is normally accomplished by undoing the air ducting to the charger.293d2a9d

If an Ecotek CB-26P device is fitted this can also be used a point to inject the PowerBoost foam by undoing the cap and removing the valve from the unit.
