There is a rumor that Pulse Plugs burn out the coils in a Yaris.... THIS IS NOT TRUE .... i bought Pulse Plugs when they first came out...at $ 100.00 a set.. <Now they are much cheaper> ... i installed them at 5k miles.... my car started skipping at 20K... one of the plugs was faulty... <it even had a burn ring around the insulator on the bad one> i put the old ones back in and it ran normally again... but did notice a big decrease in torque...especially in the upper RPM range.... they promptly sent me a new set... < at no charge, and not needing to return the old ones>... put the new ones in ...waited for ECU to adjust..... The torque was back..... even thought they had quality problems in the beginning... the Pulse plugs i have now have been in for 50K(+) ... they will send me free plugs for life... how can u beat that.... It was the Plugs not the coils... i can attest that they really work... and i'll be a Pulse Plug customer for life... Glad they got they're shit together.. ... If they burn out coils ... how do i have 90K on the original coils...????
