Fits a 89' Ford 2.9lt V6.
Fit my 1989 Ford ranger with a 2.9 lt V6. They are well priced for 4 packs, I like Bosch and will buy more Bosch products.

Quality as usual
Bosch and NGK make the best plugs overall performance and reliability... Can't go wrong with either! Use these in my Challenger RT plus and NGK iridiums in my ram 5.7 hemi as well! They perform very similar but I prefer Bosch being I have used them for decades! These are pre gapped but I always check in case someone messes up from the manufacturer!

Otorgo más torque a mi Civic D17a2
Trabaja genial, me tiene satisfecho la relacion precio calidad, otorga una inigualable potencia al motor, el vehiculo recupero torque y cuenta con más caballos de potencia que antes, estoy realmente asombrado, volveria a comprarlas, es asombroso, además al contar con mayor potencia y mejor quemado de combustible me mejoro el consumo significativo de combustible, trabajan mejor que las NGK de iridium que tenia instaladas, las recomiendo verdaderamente.

Just what i needed
Purchased for my 17 5.7L Durango RT. The gap was actually correct out of the box and the price was better than the Mopar plugs were wholesale! And i personally think they perform better too!
