It turns out there are two sizes of filter for my 07 Swift 1.5, depending upon whether the car was made in Japan or Hungary. I got the wrong size to begin with but the Pipercross guys in Wellingborough advised me and swapped it immediately. Very helpful.

Fast postage, products came as described, would buy again.

Item came next day, fab!!

What can I say.. Always get a top notch service when dealing with piper cross.. Fast trouble free delivery and a superior filter with that distinct induction sound and look.iv always have there product on my cars and this will never change.

Awesome service told me what I wanted to know with out the messing about quick delivery and great products definitely using again and would recommend to anyone

I was not sure if I needed oil for this filter ,and ordered it anyway. I was contacted by this company and told that the oil was not needed and refunded immediately. The help that I received was invaluable and very helpful. I would recommend this company to everyone

Contacted sales team to make sure I was ordering correct filter swift response and when ordered very speedy delivery and excellent product.

Fast delivery. Good Web site .great value.

Best after market product fitted and notable improvement in engine breathing and performance

TT 225 panel filter is awesome!

Really easy to find the right filter for my car. Ordered direct as the price was just as good as anywhere else and delivery was next day and free so better than anywhere else. Got it the following day and fitted in ten minutes. Car sounds great and runs perfect, great stuff.

The website is easy to use and my filter arrived very promptly despite the distance (UK to Australia).

Quick delivery but After 10 minutes of driving with the filter in my engine management light came on I have swooped it bak to the standard paper one and there is no issue a waste of money

Perfect experience, does what it says on the 'can' instantly improved how my car ran, specially 1st gear sluggishness,standard filter was strangling performance,may loose a few MPG, but well worth it. Very fast delivery, kept informed by courier what was happening,and I was able to select alternative delivery address every on delivery day so was able to keep appointment..highly recommend in all respects...

Delivery to France in 48h. Very good product quality and good following of orders status . Good supplier!!! Pièce expédiée et reçue en 48h vers la France. Produit de bonne qualité avec un bon suivi de commande. Fournisseur très sérieux !!!

Ordered my panel filter for my BMW Z4 2.2i on 30th June 2015, was expecting a 3-4 day delivery, to my surprise, it was delivered on the 1st July 2015! I was over the moon at the speed it was delivered and how polite the delivery driver was! Love the difference it makes to the car, you can feel the low down change in acceleration! Definitely when i upgrade to the BMW Z4M i will be coming back to PiperCross, and recommending them to friends and the trade i work in (Car Sales) John S Sales EAdvisor Nissan Waltham Abbey

Lets start with the price, direct from the supplier & cheapest around. Yes you will find them cheaper but add on P&P and suddenly, mmm, not so good. Service excellent, ordered late afternoon, dispatched next day, delivered in 48 hours, great ! Good communication, I am happy to highly recommend "Pipercross" without reservation, thanks Andrew.

Unfortunately the phone number on the top of their home page is for another department and not for the shop, found this to be a slight inconvenience as the operator at the other can't direct you straight to the shop and you have to redial another number. Otherwise, once you get through to the shop, I found them to be well mannered, knowledgeable and very helpful. Also the communication updates on your purchase is extremely good, from processed to despatched and onto delivery day / date / time. Brilliant

Rebuilding my Reynard FF89 for Portuguese SSS. In July there was a free delivery offer from the company. As family were travelling to Spain I asked if they would mind bringing me one. Plpercross shop promised to deliver by Monday 20th July to Surrey and family travelled on the 24th. On the 25th I received the air filter :)

Great communication, fast shipping and high quality product. I was a big BMC/ K&N fan but the service and quality from PiperCross has been so impressive I will now fit PiperCross filters to all my bikes.
