This Audi A3 1.8 Turbo Sport was fitted by Matt Rooke who first fitted CB-26P's to his BMW M3 (click here to see it and his comments), this is his wife Emma's A3 and she says it's much more alive since the Ecotek unit was fitted. Note the Pipercross filter. 

The whole VW and Audi range seem to benefit considerably from the CB-26P - there is a complete section on VW Golfs on this site (click here) which includes rave reviews by Rabbit, VW Motoring and Volkswagen Driver. Not only does the device improve petrol consumption but throttle response and general 'driveability' is improved. It also improves breathing at higher revs as the unit fits at the opposite end to the air intake. Audi owners always comment on how much freer revving the car is after fitting. Great cars made even better!

Here's Helen's Seat Leon Cupra (Cupra stands for Cup Racing) and this little beauty has 6 forward gears, traction control, the VW 20VT engine - she'll do 148 mph and 0-60 in 7.9 seconds - all this with A/C Climate control, 6 CD stack, 4 air bags and electric everything! You'd have thought that there was little more to do but the Ecotek improves cold running, low end throttle response and Helen reckons she getting nearly 10% fuel economy.

She said: "I didn't think you could make this car much better but the Ecotek has certainly made a noticeable difference - and I get better economy - I'm very pleased. The car is new but Kinghams of Croydon, who service it, fit the device and don't have any warranty concerns at all".

One of the easiest to fit is the Rover 4 series and here is the Rover 416 GSi where the owner says he is getting more than 25% improvement on a motorway run.

Here we have a petrol injection engine which might not benefit quite so much from the improvements in fuel air mix but certainly benefits considerably from the swirl created in the inlet manifold.

We know that the turbulence created in the induction gasses creates a better suspension of the petrol molecules and thus a cleaner more efficient burn. It has certainly worked for this car which the owner says is noticeably more responsive as well as more fuel efficient.

Here is the Rover 400 2 litre with a red 'Combo' (a red Ecotek CB-26P with matching Pipercross filter silencer). Unlike the 1600 4 series the servo pipe on the 2 litre is narrow gauge and needs to be sleeved over with 10 mm hose and four 14mm jubilee clips. The effects are significant on these engines with a noticeable improvement in throttle response and 10% plus economy improvements. In all cases fitting is very straightforward - the sleeving on the 2 litre requires a little preparation but the servo is very accessible and the whole job shouldn't take more than 20 minutes.

This Peugeot 205 GTi belongs to Steve Silk from Fast Car (see the link below to read his review) - these and the 309 GTi's both suffer from very lumpy tick-over and rough low end performance (sometimes known as 'Kangarooing'). After exhaustive tests at Motoscope they said: 

"Up till now the only real solution to this has been to modify the ECU at a cost of £240. We recently fitted the Ecotek CB2-26P to one of our own 1990 Peugeot 205 GTi 1.6’s and tested it on our rolling road – it took only 10 minutes to fit and immediately reduced CO emissions throughout the rev range. The car drove much more smoothly, was more responsive and the tick-over rock steady at 1000 rpm".

Say no more - thanks guys!
