#22 Hi John, There was a guy called Ethan King on the Caterham FB parts group after a 420 inlet manifold if you wanted to split your parts for sale? I sold my old manifold and air box on there within a couple of days. Paul

I had the Caterham factory RBTB upgrade done from new when I bought the car in December 2020. I just found the standard induction noise a bit, well, quiet! The noise with them fitted was worth it. Unfortunately something has gone wrong with them after 500 miles driving and they're being completely replaced ( I don't know what's gone wrong as they can't tell me - the car was in for a huge list of warranty issues, kangarooing and hesitation at 1500-2500rpm being one of them). All being replaced under warranty by CC and they've been very good sorting all the other issues so I can't complain. However, if I'd bought a car that wasn't new and was out of warranty I'd have gone with the Premier Power F225 upgrade. Stuart is well worth talking to http://premierpowerengines.com/premier-power-f225-upgrade/
