Excellent albeit a bit pricey for what it is. Noticed an immediate improvement on performance to Vectra SRI 2 litre turbo. Now derestricted the air box, opened up the air intake and using vpower petrol with additive. Sent the ecu back to factory settings and - woomph Next thing remap but that's even more money for what it is so maybe a vauxhall mechanic into remaps is doing for a drink - a few minutes work by a pro. Now maybe performance spark plugs...

I got a K&N filter to put in my Corsa C model 1.4cc and I liked the sound of the air intake. I believe that a possible increase of horsepower about 2 and 4 hp.

A doddle to fit as a direct replacement for the standard filter. The improvements provided by this one little mod to my little Tigra twin top 1.8 have been excellent. I'm not so interested in ultimate top end power on the road, but the improvements in pick up from low revs and the improved acceleration are fantastic. The K&N filter has actually made the car easier, and more enjoyable to drive when I just want to pootle around, and provides much improved better throttle response and acceleration when I'm feeling a bit more feisty. It may have made the Tigra a tad more thirsty, but 50 of that could also be down to me enjoying the extra shove you get when you put your foot down now. Well worth every penny.
