Description
DEI recognized the need for new Turbo Shield applications, and now offer Turbo Shields in the smaller turbo sizes. Unlike cheap, knock-off copies, DEI Turbo Shields use an exclusive combination of premium heat resistant textiles and newly designed stainless steel attachment anchors. DEI Turbo Shields are used to maintain a more consistent temperature in the turbo, increasing efficiency and decreasing turbo lag. In addition to Garrett® brand turbo housings, the ONYX Series™ Turbo Shields will fit several other popular turbo brands including Mitsubishi® and others.

TURBO APPLICATION GUIDE
Measuring your turbo size
DEI Turbo shield sizes are based on two basic measurements. The first measurement is the circumference of the turbo not including the flange. The second measurement is the width of the turbo at it’s widest point not including the flanges. After measuring, refer to the chart below to find the correct shield.
Our T22 and T25/28 shields are designed for use on internally gated housings. They will have a cutout in the wastegate area to allow for a tight fitment.
