This is for a Lotus Elise and the air box is hard enough to get to. It was difficult to get the box closed once the filter was installed. I think I am going to buy your cold air intake for the car. I use your filters in all my vehicles.

Great to read all the testimonials, and I'd have to say that having used K&N filters all my days - I would agree with all the praise!

Now a bit older and owner of a Lotus 1.8 Elise S, I needed something to make this already special car even more exiting. So fitted the Apollo kit and must say that this is the best induction kit I have used.

The extra sound from the Apollo is only apparent when the gas pedal is almost at the end of it's travel, so there is no kiddy boy-racer sound to be had here!
Extra flexibility is evident throughout the rev-range, and the car pulls much more cleanly to the red line - just what I wanted!

Other kits don't come close when it comes to vehicle application suitability, and it is obvious research and design time/energy has been put into making this great little filter work for my car.

Criticisms would be the slightly cheap plastic which broke from its thread used in the 1/4 breather attachment (goes into the new moulded intake pipe) I fixed this with trusty 'ISOPON P38 easy sand'
Elise owners - DO NOT tighten this to the end of the thread.
The instructions- although detailed, should include removal of the wheel and inner wheel arch lining to access the air-box clips and mounting bolts, and for easy instalment of the new flexi-pipe which sits at the car's side vent.

Thanks K&N and good job once again!

A little tedious to install as the engine bay is tight for space. Ended up buying a couple extra hose clamps for the flex hose,which was a little long. After trimming the hose the air intake was in a good spot. Took the Lotus for a drive.It started and ran fine.The sound is perfect. At part throttle, it is as quiet as stock.When you open the throttle it sounds fantastic! Exactly what I wanted. My sons drive the car and they wanted more noise.They were so excited and happy with it.They thought we should get an exhaust, but I knew that would have been a real hassle. Love your filters. I've used them in all my vehicles for years.This is my first intake and now I'm tempted to get one for our Honda Civic.
