I'd order the K&N from dreamscience. But I must add when I went to dreamscience the order of K&Ns hadn't come in again as K&N have been letting them down with deliveries so Jared did me a massive favour and said he would go to halfords and get a temporary filter to put on then send me the K&N in the post. It was a ripspeed filter and it looked similar to a K&N but costs only £27.99.
I was gobsmacked when we put it on the rollers and my car made 305bhp and 355ftlbs torque.
It felt good on the road too pulling early and now I have the K&N installed I can actually confirm the HALFORDS/Ripspeed filter whistled and dumped louder.
I am going to see the difference in results when I get my car rolling roaded again on feb 6th and decide whether to change back to the cheap ripspeed filter.
Jared is actually trying a BMC filter in his at the mo which BMC say is their best.
not sure I would trust a Ripspeed filter to actually keep the dirt out of my engine, which is what its actually there for...... K&N or Piper would be my choice depending if you want foam or pleated, as sold by DS....
