[BenEP2]

hello im a newbie, i have a 98' altezza rs200 auto and im looking to change the current spark plugs for better ones but im unsure of what grade ones to get? i live in the south west of england. are the long ones of not??

Im also interested in buying a Blitz panel filter as i heard that the stock airbox is best. any help welcome.

Thanks Ben

Just run with the standard heat range but change to an iridium plug. Denso IK20 or NGK BKR6EIX11 are the two best options for he 3SGE.

Pod filters cause a lot of hassle & are expensive. A decent panel filter is all you need. There's a flap in the top of the air box that opens at @4000rpm. You can disconect the vacuum line to it so open all the time if you want a bit of induction noise at lower rpm.

If you haven't cleaned your MAF sensor & throttle body yet, do it asap. You'll be surprised at how much difference it makes.

Best to use Denso or NGK plugs with the Toyota engines- they don't like Bosch plugs for some reason.

I'd recommend using Denso IK20 plugs

Make sure the throttle body and MAF sensor is clean. You possibly need to look at the fuel injectors, they may well be leaking and/or not spraying correctly and need to be replaced.
