Bosch S3971 Car Air Filter - Separates Particles from the Air Intake - Moisture-resistant plus High Tensile Strength

First class fit for my Citron c1 good quality.

Yes good.

I recently replaced the air filter in my 2012 Toyota Aygo 1.0 Fire, with this filter.The process of changing was as simple as opening four clips, lifting a cover, taking out and replacing the air filter.Immediately the car has much more power, it accelerates noticibly quicker. It would stall regularly when pulling away and I thought that it was the clutch that required replacement, but changing the air filter seems to have done the trick. It pulls up banks too, I'm expecting to see an improvement in the vehicles mpg, I have been getting 53mpg but hopefully it will give over 57mpg, though I'm a couple of weeks away from that calculation at the moment, I will update this review, once I have the data.

Fit with my car and nice delivery

Value for money

This filter was certainly much better than the filter it replaced.The quality appears to be very good and it fitted perfectly into the filter housing without any need to dismantle the filter box itself. All I had to do was release a few clips, lift the lid up as far as possible and drop the filter in, making sure it was seated correctly to allow the cover to sit flush.Piece of cake.

Easy to fit in place, works very well

Bought to replace a grubby filter that should have been replaced long ago, so obviously I’ve seen a massive increase in fuel economy.Great quality as expected from Bosch.For the price I’ll be replacing these much more often just to keep all in good order.
