K&N Filters 33-2955 Replacement Air Filter, Heather Red

Fitted to a 1.4 tdci 2011 fiesta. The filter fitted fine but it took a fair bit of research to confirm that it would. In the end I found the Ford part number and then used the cross reference chart on the K&N website. I did not buy this for any performance improvements but for the ease of maintenance and cost savings. Even OEM filters for the car cost around 16 pounds so after just 2 replacements you break even on the cost of this filter. Also the filters are of much better quality and unlikely to fail like the cheaper paper ones. I always fit K&N filters to my bikes and cars for these reasons and have always been happy with them. As to improved fuel consumption and performance these may well improve a bit but only if the original filter wasn't flowing as much air as the car needed. I have noticed a small difference over the OEM filter but very little over the original that was fitted. But this is on a 68hp diesel bought for economy, not performance. So this filter can perk your car up if the original filter was bad or dirty, but its better to think of the main benefits being better quality, longer life and less frequent maintenance. Then any performance improvements are a bonus.

I purchased this air filter to go in my 2014 Ford Fiesta Zetec S. This item arrived the day after ordering thanks to Amazon Prime. In the Box you will find the following:-Air Filter-Installation guide-K&N window sticker-Air filter "Do Not Throw Away Sign" This is to be placed on the air filter coverNOTE#####It is probably best to have the following equipment ready if you are installing the Air Filter to your car:-1 phillips head screw driver-1 flat head screwdriver-1 rag/cloth-1 black bag/ carry bag (to place the old filter in for spares)Installation#########On the Ford Fiesta:1. Open the bonnet2. Locate the Air Filter Cover (big black cover on the right of the engine bay, has a big rubber pipe leading to it)3. Remove the Air Filter sensor attached to the big rubber pipe. This is a wire attached to the Air Filter intake to the engine, lift the red tab then pull out.4. Loosen the engine Air Intake pipe from the Air Filter using the Flat head screwdriver.5. Pull the Air intake off the Filter cover.6. Now take out the Air Filter cover screws (1 in each corner) using the phillips head.7. Lift off the Air Filter cover and remove the old filter (keep this if it is clean, just in case)8. Place the new filter in and reverse the process.NOTE#####-When replacing everything, be sure to attach the Air Filter sensor or else the car won't start due to it thinking there is something wrong with the Air Intake.-Try to use short screwdrivers as you will need to get your hands around a few objects.-This is an lubricated filter so expect to have some oil on your hands and engine bay.OVERALL#########It may just be me but I have noticed a marginal improvement in economy. There is a noticeable difference in running and idle noise with the K & N fitted to the engine. For that reason alone I would suggest to purchase a k & n for your car, it adds a meatier sound to the engine especially when pulling away from stationary.Overall a good product.NOTE#####When ready to clean you will need to follow the recommended guide, this involves using k&n oil based sprays (sold separately).

Previously had one of these air filters but appears it got pinched by my mechanical. After feeling like the car was a little down on power on the low end I checked and yep paper air filter was in its place.Does this really make a difference. Not a huge deal but I can notice in the low end where the 1.0 ecoboosts struggle it helps out. The engine also feels like it runs a little smoother. It won't make a difference anywhere else but that low end. Also if you want to hear the engine a slight bit more this can help.This is not a must have item but if you want to squeeze every last drop out of your car without properly modding it, it's worth considering.

58 plate 1.4 Fiesta petrol. Took 5 minutes and a Torx screwdriver to fit. Piece of cake. I notice that the engine revs quicker and sounds smoother too. Definitely more responsive. The flat spot between 1100 and 2000 revs is smaller. It feels more powerful but that may be my subjective experience. No detriment to the economy.

This is a decent quality air filter that will probably outlive any car it is installed to. Torque and horsepower have noticeably increased and there is a lovely purr from the engine at higher revs, hence why this has increased my fuel consumption as I can't stop listening to that beautiful noise coming from the engine. I do not know if it will help my mpg when I start driving normally again but I will update this review accordingly if I find any change.EDIT: I've had this in my car for almost 4 months and there have been no problems or complaints. The engine noise is a lot nicer and I get about 2-3 more mpg. I will be upgrading to a lnms&tbm induction kit soon and I will be buying from K&N.

Fit's perfect for 66 plate 1.5decosport.

Didn’t fit my car, thats why im returning.

I bought this for a 5 year old Fiesta 1.6 petrol. The original filter was clean so you will only really notice a big difference if you were taking out an old dirty filter. But I still noticed the throttle response is slightly sharper, it's more willing to rev and it sounds like it's breathing better and of course you don't have change the filter every year like before.Just take it out one a year and give it a clean as per the instructions and it should give you good service. It won't turn your average car into a fire breathing hot hatch but the benefits are there.
