I bought the intake purely for cosmetic reasons and the fact that it's an official Toyota part, so there would be no warranty 'issues' if the car was to end up at the dealership for some other reason and they saw it under the bonnet. Any performance improvement noted from the dyno tests online are just an added bonus for me - I don't notice anything tbh and certainly can't hear any louder induction sound.
I bought mine from
86Speed in the US. At the time it was $550 (it's now on 'sale' at $502), plus $151.50 for priority shipping. Fedex and UK Customs stung me for £117.31 at the border (others have paid less). All in a total of £664.22 compared to the local Toyota Dealer who quoted me £1,038.
