I didn’t have a geo check but I do get the car checked regularly (12-18months) usually triggered by minor maintenance.

I briefly tried the cold air induction kit. Top end noise improved but it created a slight and short lived resonance “buzz” as I punched through 5000rpm which I just didn’t like. I’m open to offers if anyone is interested.

Yeah I’d agree on the resonance point - for me it’s at 6k and I don’t mind it, but would be ideal if it weren’t there. I was planning to see if adding a little bit of strengthening to stiffen the box may help

Yeah I didn't like the resonance either. I had it in for a good 6 months my wife and I both used to feel sick on journeys. As soon as reverted it back to normal, which it has been for another 6months the sickness feeling went away.

I reckon it was something to do with frequency of the resonance.

I have never heard of this before with this kit.yet a few of you mention it. I certainly didnt experience it in mine. just out of interested have you all reverted totally back to stock or kept the sports filter but removed the hose and bung. Question

Cold Air Induction kit removed and up for grabs. I was toying with giving it another go but think I’ll stick with the stock air box set up.
I’ve kept the BMC filter.

You can buy my CAI for £50ono plus Royal Mail P&P. All black. Brand new and I only did about 20miles before I removed it again and reverted back to standard.
I bought the BMC filter from Eurocarparts.
