Looked at these and I cannot believe the price for an intake on these cars. Fair enough the likes of Forge with the twin intake but you can make your own using the standard MAF housing as above for about £100. Look on Silicon hoses and you can get two 90 elbows for £35, reducer for £13, 1m of 3in tubing, some hose clips and a generic sized filter. If your worried about heat then wrap the back pipe section in heat resistance tape for an extra £20.
