Sirion 1300 SL / K3 VE2 Iridium Spark Plugs. Also Rally 2 / 4.



These plugs are an upgrade to the standard plug for the above Engine. Yes they cost more but in my humble Opinion - Are worth every penny.

NGK Iridium Spark Plugs


Also last a good 60,000 miles and more. Smile


Have used these before in my YRV Turbo

Used these a couple of years ago in my YRV Turbo, K3-VET engine. First impressions were they were okay, but felt that I lost power with these fitted. Cannot prove scientifically but it just felt that the car had less go, you may prosper from better MPG though.
In the end went with a colder NGK plug which is meant for the Subaru Impreza STi EJ20 2 litre 16v boxer engine called the NGK PFR-7B.
