Specially designed and developed in conjunction with Pipercross exclusively for the Ecotek CB-26P. 
 

The Filter/Silencer was created at the instigation of Mike Buckler of Gatwick Alfa. He builds racing and rally car engines and uses the CB-26p. He found that on engines used in rally cars on the East African rally the device would clog up with sand and dust after only a few stages. Shown here with the Ecotek CB-26P you can see how the Filter/Silencer fits over the intake of the device and clamps over the locking ring making sure the device stays locked. 

In conversation with Pipercross we discussed the use of sound deadening foam and discovered that they have a 60 micron fireproof filter foam that also acts as an acoustic baffle. We know on certain cars the induction noise made by the Ecotek CB-26P can be intrusive - especially for those enthusiasts who have tuned their induction profile. Accordingly, the device substantially reduces the noise and, of course, considerably extends the operating life of the device. 

It is now made in anodised Gold to match the CB-26P and Red and Blue units are available as a matching combination.

"Back in our April issue, I fitted an Ecotek wonder widget to Paul ‘The Squirrel's’ 205. What it did was help sort out some of the problems he'd been having with it - it made it start easier, run smoother and all but cured the kangarooing they all seem to suffer from. One thing Paul mentioned was a 'chirping' noise coming from his widget. Another quick chat with Mr Ecotek, to tell him of the noise, had him say 'leave it with me'- so I did.

When fitting the Filter/Silencer do remember to make sure the 'T' piece is good and tight to the gold body of the CB-26P so as the extra weight of the Filter does not unscrew the device under vibration - a 19mm spanner will do the job.

Tests show that the device performs perfectly with the Filter/Silencer in place and there is no diminution of the benefits of the Ecotek CB-26P. Increasingly the Ecotek is being used on more modern and more sophisticated cars with quieter engines and the demand for a suitable silencing device was considerable. Remember also that the device makes less noise as it beds in, so after 1-2000 miles a device with the filter fitted should be completely silent.

Pipercross has an excellent reputation for performance filters and are well known in racing and competition circles. If you would like to get in touch with them they can be contacted via: www.pipercross.com

Given that a substantial element of the turbulence created by the Ecotek device is caused by resonance the entire device would have to be encased in foam to make it completely silent – this is both impractical and expensive. Accordingly, the existing Pipercross device is considered to be the best compromise. With a new unit, on some cars, the noise can still be rather harsh. You will be pleased to learn however that the noise will get less as the device beds in and after a while it will reach a level where the Pipercross unit will have sufficient effect to silence the CB-26P completely.

This is because there are actually two noises – one is resonance in the Ecotek unit which reduces as it beds in, the other is induction roar which is dealt with by the Filter/Silencer unit. There is a video of a fitted device and Pipercross Filter, with a sound-track of the noise heard above an engine fitted with an induction kit - click here to view.

Filtration on the device without the Pipercross unit (the gauze on the CB-26P) is 250 Microns. The Pipercross filters at 60 Microns making the device virtually maintenance free. The Pipercros filter can be cleaned with domestic washing up liquid but shouldn't need cleaning for 20,000 miles. In dusty and polluted environments it is highly recommended - alternative crankcase filters are not suitable as they filter at 500 microns.

The all British design and build of the Ecotek system is being maintained in this further development and the no quibble satisfaction guarantee is, of course, extended to this excellent Pipercross product.

The price is £16.95 plus vat and £1.60 post and packing. (Total £21.80 inclusive). It is available singly or together with an Ecotek CB-26P. Red and Blue matching units are only available as a complete pair (referred as a 'Combo'). The Filter/Silencer simply slides over the body of the Ecotek device and is secured by the supplied nylon ratchet.
