Today I changed my Engine Air Filter.
I yanked on the old PENTIUS air filter and it was sturdy.
It was fairly dirty but could have gone 10,000km longer for sure.
I cut the old PENTIUS up, and it was Synthtic media, I thought it was paper.
Cut it with a knife, and didn't look close to being full of dirt.
Yanked at where it was bonded, strong stuff.
Order Ecogard or PENTIUS with 100% confidence.
