just curious, for the price if they work, then they could be worth it

When something is supposed to do as that says and it's £2.99 then I'd question whether it's genuine.

When it's £2.99 and buy it now on ebay then.............

christ that IS local too!

Checked his feedback, good but the first 25 dont include this mod, a lot of other bits and bobs though

got a lot of them though

Yeah wonderful, so you pay 2.99 for a 20p resistor and instructions to fit it to the lambda sensor ... or somewhere similar. 20 bhp my backside.
Snake oil , load of crap . If it made 20 bhp dont you think we would all have one.
Should be banned from ebay, all it does is make your car run lean. This will give quicker throttle response but nothing worth the risk of it going pop!!
Steer clear.
Just on an alternative if a k and n filter and open exhaust dont give those results why would anyone believe the claims. The alternative one i have seen for sale is a variable switch....still crap.

ECUs are well complicated peices of kit and I wouldn't recomend b****ing abvout with one in this manner.  Firsly it may not be legal.  Secondly if it creates a false air temp reading then the Lambda sensor will just correct any change, although you may get a fault code at your next dealer service.  Additionally  it will only fool EFi that uses volumetric ari flow sensore, like the flapper Range Rover EFI, a mass air flow system will not be as easily fooled by a spurious air temp sensor output.
Snake oil, I call it dung.  I could understand if it modified the sensor reading in line with the actual air temp but to fix it at one setting?  Car may not start some days!

The earlier replies are spot on, you are getting a resistor worth a few pense and details of where to 'ram it in', I was considering buying one of these (or one similar) for my Audi, but I knew there must be something wrong so I contacted a previous buyer, who gave me the number off the resistor and told me where to put it, but although he did think he had more power - he felt the engine was running a little 'rougher', so even with the few pence upgrade available, I didn't bother and I don't personally thing you shoulld either.

we used to do a similar thing to Astra GTE’s and such, whack a resister in to make the car over fuel. But std car ran rough, needed to add decent exhaust and a top quality air filter to start noticing any difference (on the astra with a good sports exhaust and air filter plus resistor you would prob see a 20 BHP gain which made a big difference due to weight) and as you can guess used a lot more fuel.

 Better off getting a professional chip upgrade, so only over fuels when you stomp your foot down, which means you can get a better fuel economy, as they can set it to run more economically around towns and with normal driving.
