It's time to give the car a once over.
Question is the plugs
Heat grades and gaps?
To my understanding they should be pre gapped? Also getting in a mucking fuddle over the heat grades 6 are the colder plus rights and for standard cars? But I've read that people run 7s no issues? Also do I get platinum tips or iridium tips?

Second question is panel filters? Had K&N panel on a previous car and had was fantastic but I'm reading that after a re oil the can clog the MAF? Are they're any other alternatives for reusable air filters?

Thanks

 

PFR6B for standard
PFR7B for modded (I run these with a slight boost increase on my Type R),gap is 0.65 to 0.7 normally.

They come gapped buy you should always check the gaps before putting them in.

I've a STI panel filter gets checked every year and only needs a quick dusting off.
