K&N 57i Series Induction Kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N O/E replacement filter which is always limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

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.
