Could anyone please tell me how long it would roughly take to fit the intake in question? mine turned up from a member today just wondered if I had time to fit it tomorrow after work as it quickly gets dark. Not had chance to pop the bonnet and work it out. It looks a simple job. Just plug and play? Is the airbox bottom half fitted in with rubber grommets like the engine cover also? thanks for any advise. Also I presume it's a easy enough job to fit the standard back on?
