Review: Cool - Very good product. I recommend the seller. Fast delivery, everything as described. 100% satisfaction.
Review: Buy it! - Was watching this item for a long time whilst it sat at around £55. Just picked it up on a deal at £41ish and instantly regretted not paying the higher price sooner. All in all, I'm chuffed with this filter. So, if I hammer it, I get worse mpg but better performance. That's fair and to be expected. But for everyday driving, I see massive gains in throttle response, and slight efficiency gains too which was a plesent surprise. It's been a while since I used a K&N filter and although throttle performance was a key driver in this purchase, my primary concern was impact to efficiency (mpg). As I had recently performed a full service on the car, I was able to directly compare a new OEM filter against the K&N. This is in no way scientific but here goes... Having the OEM installed and the drivetrain up to operating temps, I reset the trip computers and performed a 5.5 mile test on a quiet stretch of dual carriage way with the cruise control set to 70mph the entire time. The test included downhill and uphill sections of decent gradients as I wanted to test the engine when coasting as well as under load. After the OEM run, I immediately swapped to the K&N and performed the exact same test, maintaining the same conditions (weather, outside temp, no traffic, electrics such as radio and lights unchanged, everything but slightly less fuel). With the OEM filter, I achieved 52.1mpg With the K&N filter, I achieved 54.7mpg So, not a great improvement. But the main purpose of this test was to ensure no dip in efficiency under everyday commuting. However, this test ignores other benefits gained from having the K&N installed: - Under heavy load the car sounds a little more grunty. It's barely noticeable but it's still an improvement. - Throttle response has vastly improved. This was a big surprise to me. I was expecting some gains in this area but this filter has changed the car completely. I've lost a flat spot at the low end, turbo lag feels pretty much gone and the car generally feels more awake and in touch with what I'm asking of it. This is exactly what I wanted but didn't think was possible from a simple filter swap. Test engine: Vauxhall 2013 2.0CDTI (165)

**Q: i have a 60 plate astra 1.4, would this still fit in my car?**
A: I fitted the filter in my 2013 1.7 Astra diesel and it added I would say 5-10 more power and economy.  I do not know if it will fit your 1.4 Astra.  I would check with K&N and your local Vauxhall / Opel dealer.  Best of luck with that one. Ian

### ⭐⭐⭐⭐⭐ perfect
*by D***O on 15 July 2024*

if looking for extra air displacement and don't want an induction which in my experience can drag hot air as well as cold from engine bay this is way forward and not breaking mot rules as direct fit but allows so much more air , throttle response, I'm shocked coupled with a few other things people would be so worth the money. also you don't change them clean and re oil done. and instead of every service 50,000 miles or more clean. So much better in my opinion. mot take out put original in so no one takes it. but easy to fit .
