I ordered this kit on Tuesday night, and waited eagerly for them to be delivered.
On Thursday they were delivered to my work address, and I quickly ripped open the very well wrapped box - it was like christmas, and had a good look at the kit - very well made it was too, nice and shiny red, and almost the same colour as my Velocity red mx5 - really close actually, and since it is metallic paint, it looks like a matched colour.
I has to stare at it all afternoon, dying to get it fitted, after reading the other reviews, I was not actually expecting my difference in normal driving, but I thought - well at least it'll look cool.
Got home, fed the cat, and got out my tools, all I needed was a smallish flat blade screwdriver, a 12mm and 10mm bit for my mini ratchet set and a couple of extension bits so I could reach the difficult bits in the engine bay.
It took me a whole 30 minutes to fit, and that was with a cup of coffee and a couple of checks I'd done it right - I am quite a practical person, but since it took me so little time, and all the other reviews seemed to talk about 45+ minutes, I was doubting myself...
It was easy to fit, the instructions (which are also availible here http://www.kandn.com/instructions/69-6000.pdf ) were really good, and as long as you follow them step by step, I cannot see a possiblity of failing!
So, I fitted the kit, and checked a few times, made sure that everything was nice and tight, and the reconnected the battery, and had a ciggie whilst faffing about restoring all my preferences on the radio. Once this was all done, I started the engine. All was fine and I revved it a bit, and then checked once more that nothing came loose or looked wrong - it all looked okay - had a bit of a funny hissing noise coming from the filter, but since it is much freer flowing than the standard fitment of the airbox and resonator, I thought this was okay. Revving it in neutral made no real difference to the noise at all, so I closed the bonnet and decided to take her out for a spin.
Well this "spin" lasted a few hours, and involved a fair few miles, including a trip out to show my mother!
If you keep the engine load light, accelerating gently, there is no real difference up to gone 4000 rpm, and if you are driving gently, you will not get over 4000 rpm anyway... but.... put the engine under load, and you get the best Rharrrrrrr noise, it sounds wonderful, just like a sportscar should be. you don't need to 'rag' it to get this noise, I found that just pulling away 'normally' done it. :o)
If you pull away like you mean it, it makes the best noise ever, a wonderful deep throaty rharrrrrrrrrr, right up to the redline.
As you might be able to tell, I am VERY impressed with this, I always felt the mx5 was a great car, but lacked that noise a proper sportscar should have, this goes so much to give the car that 'something'
I am now seriously wondering if I should bother with that nice stainless steel exhaust I was thinking about - I thought it had to be the exhaust which needed changing to get the noise, but maybe I was wrong, or maybe i'll get it anyway to make sure :o)
On the performance improvments, I have to say, on the roads I used, I am not convienced, yes there might be an improvement, but to tell for sure, you'd really need a dyno, as it is very slight, K&N talk about a 3.7HP increase (on http://www.knfilters.com/search/product.aspx?Prod=69-6000TR ) and really that is nothing... we are talking about going from 147 to 152, I really do not think most people would notice that difference - a bag of spuds in the boot would probably make more difference than that!
But the noise is worth it!
I have to say, in finishing, that I was very impressed with mx5parts.co.uk, they delivered on-time and even gave me a great answer to my bugging email I sent.
Now, what do I do with the old airbox and bits????
