do mine meself mate and they aint that bad,if your cars got std airbox that has to come off,aswell as the washer bottle you can then get at the plugs with plug socket and 2inch extension/ratchet cant see em or where they screw in just the holes,to an extent its done by feel so be careful, , especially coz with yours i believe theres individual coil packs per plug that have to come off first and can be tempremental once removed.(got blitz irridiums in mine ok but not a real noticeable difference)

I'd go for the NGK PFR7B's gapped to 0.7mm
since you have an induction kit you can get to the OS plugs, NS you have to remove the washer bottle.
You have to remove the coil packs, just 1 10mm bolt and pull them out, then I use a small socket extension with the sparkplug socket - handily its just the right length. Top tip is to remove the rubber in the spark plug socket, otherwise once you've tightened up the plug you can leave the socket behind - only option to retrieve it is to take the plug out again
Last thing - don't overtighten the plug, you should be able to 'feel' the washer crushing down, then once it goes tight I give it another 1/4 turn
