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

On time delivery and perfect fit for fiesta 2012,1.25. Slight change in sound and felt engine more free. Need to check change in mpg.

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.

Quality filters at a decent price easy to install as same size as standard filter but longer lasting

I feel like there is less lag on the turbo, the new, smaller K&N filter helps the engine catch it breath quicker and feed air into the turbo. Also get a better 'suction' noise from the engine bay which just sounds slightly better. Filter should also last the length of the car, just needs cleaning every now and again. I would reccomend getting this if not ready for the full induction kit.

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.

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 cover NOTE ##### 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 bonnet 2. 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).

Didn't fit properly. Used it in my daughter's car, older model, fitted fine in her car.

I have used these panel filters on two of my previous cars. They do not give you significant gains in power but they do increase it and reduce fuel consumption. The new panel filter is fitted to a Ford Fiesta ST-2. the installation was quick and easy providing you know what you are doing. as soon as it was fitted and the system bolted back up I noticed a change in the tone of the engine. it was also running smoother and there is less delay in the turbo kicking in. I would absolutely recommend this to anyone as it will improve your fuel economy and give you a little bit more power.
